Although more have considered it a type of pre-cursor to monotheism thither is no proof that it was neither was it polytheism. It was actually a quasi-blend of the deuce more associated with the New Age religions, also known as henotheism. Atenism as Related to Henotheism, Monotheism, and Polytheism Initially peerless can say there are elements of monotheism, polytheism, and henotheism intrinsic to the ancient Egyptian religion of Atenism. In taking a closer look, Atenism is not polytheism, the worship of many gods and goddesses, or monotheism, the worship of superstar close and mortal-to-person god, exclusive of all others, but more closely related to henotheism, a blend of the two where there is one main deity, either with multiple manifestations and names, or one main deity with many associates. era early Egyptologists felt that Atenism was a predecessor of monotheism, there has been no proof linking that cult with todays traditional monotheistic beliefs. (Lawlor, 2007) Atenism is the religion associated with the worship of Aten, the sun disk, who until about the 12th century B.C., was just one of the many gods and goddesses associated with ancient Egyptian religion. ... worship of other gods was permitted however within five years of its portal Atenism had become the supreme religion with only one Supreme Being worshipped.

There is some speculation that since pharaohs were thought to be deity personified that perhaps Akhenaton was, as well, the messenger person for Aten. (Geller,2002) With the installation of Aten, nine years from the beginning of Akhenatons reign, all traces of Amun, the previous supreme deity, were erased even to the dot of chiseling the inscription off of temples, statues and entering tombs to remove all traces of the thrower deity. This was a common practice aimed at removing the old and instituting the new as though the old never existed it continues with Egyptian history today, as the case history books are re-edited with the installation of new leaders, showing the previous leaders as ineffective and requiring replacement. (Geller, 2002) In Atenism, God is seen as loving and beneficent, protecting and supporting his people through his very presence, which is real enough, though not personally involved. He is not seen as authoritarian, judgmental, and justice-oriented. The worship of idols was banned, and all references to Aten in written form were shown using a sun disk whose rays culminated in upraised h ands. Later, Akhenaton permitted it to be written phonetically a symbol of his radicalism in the new religion.

Tsotsi directed by Gavin Hood and Chris Abanis Nigerian novel Graceland Essay Example for Free
Tsotsi directed by Gavin stumblebum and Chris Abanis Nigerian myth Graceland EssayHow do the name of main characters in the film Tsotsi and novel Graceland situate their identity?When comparing the reciprocal ohm African movie Tsotsi directed by Gavin gawk and Chris Abanis Nigerian novel Graceland, both are stories of young men struggling with their poverty-stricken fates. In these African cultures, the names of telephone exchange characters Tsotsi and back breaker are more than just a reference they carry the clues to their past and the explanation to their chip in as they endure journeys of self-discovery. In the film, main character Tsotsi embodies his native label. In the local vernacular of South African townships-comprised of Afrikaans and a mixture of local dialects such as Zulu, Xhosa, Tswana and Sotho-the term tsosti can literally be translated to thug. With it be intimates the historical association of the 1930s urban youth combinations that ruthlessly ruled a t the twinge of the ghettos hierarchy. Although in the past the name tsotsi carried a glamorous gangster image, the word is now used to specify displaced young criminals. This history of the word parallels the characters past. Tsotsi is seemingly comfortable in his role as a cold-hearted gang leader, but the viewer questions his motives as the film progressively exposes his troubled past. Hood uses flashbacks to portray Tsotsi as a young boy in his last moments with his bed-ridden breed.As he reaches out to hold her hand, the scene is slow-moving as if visually symbolizing the strength and endurance of their love. In these defining moments, his mother calls him David-meaning belove. The appearance of Tsotsis aggressive, intoxicated father triggers a sudden change in pace-a rapid series of individual close-ups foreshadows a flood tide in the conflict that willing permanently paralyze the characters frantic acceptance of each other. Parting from his mother metaphorically displa ces David from his once safe, loving past to Sowetos perilous grasp. When he runs away, he leaves behind his objective name-his confessedly identity. The new name Tsotsi allows him to take on the role of a nameless thug that masks his emotional reality and provides him with an outlet for his traumatic childhood.In Graceland, the main characters name is inspired by the late Elvis Presley. throughout the novel, Albanis choices of names define a culture in which all you had was your name(187). Before money became a frequent determinant of status, the sole measure of a man was his name(187). Elviss father, Sunday, lives to take the family from being a nobody to carrying a name people spoke with respect(187). It is therefore untraditional for Elvis, as a future male object lesson of the family, to be named after his mothers, Beatrices, unaccredited passion. This act alone foreshadows Elviss inability to satisfy the conventional role pose upon him in Nigerias male-dominated society. Beatrice, meaning bringer of joy, invests her love and passion for symphony in Elvis. In the same way harmony acts as an escape from the slums grim conditions, Elvis is Beatrices symbol of hope-an innocent new beginning to life. Both Tsotsi and Elvis define their names through the strong connection with their mothers. When Beatrice dies, Elvis loses his source of inspiration, and the reader questions whether he will still be able to live up to his name. Both Tsotsi and Elvis found motivation and train in their mothers care, thus struggling to maintain paths of righteousness(171) after their loss.Although initially thriving in his self-adopted role as criminal, Tsotsi is eventually forced to come to terms with his align, restrained identity. In the beginning, he organizes crime with his followers capital of Massachusetts/Teacher-boy, Butcher and Aap (monkey in Afrikaans) at his heels. Together the meanings of the three names describe the characteristics symbolic of a stereotyped street gang an abandonment of education, a bandingbaric desire to hurt and kill, and the foolishness of reckless animals. in spite of the gangs obedience, it is not long before Bostons guilt consumes him after a murder, and he begins to question Tsotsis mysterious faade.He verbally tears at the mask Tsotsi has created Whats your name, Tsotsi? Your real name? Thug? Thats not a real name. The interrogation triggers Tsotsis angry past and fuels a brutal beating of Boston. In the following scene Tsotsi is fleeing the bar, and Hood parallels the event to the flashback of David originally running away from his father. Hoods cross-cutting implies a commonality in Tsotsis state of mind during these both events. Tsotsi has become exactly what he ran away from all those years ago-a bitter, drunk abuser. This inner realization forces Tsotsi to come to terms with his past and re-establish his true identity.After Beatrices death, Elvis struggles to maintain a source of identity. Beatrice has endured him with the role of her idol-she loved Elvis Presley(105)-and Elvis soon begins to physically embody this responsibility. His first job in the novel is socialise beachside tourists as an Elvis impersonator. While Tsotsi hides from his real name, Elvis tries to embrace the inspiration behind his. Unfortunately, in a life where money overrules passion, dancing is not seen as a sufficient job it is something everyone does in de bar on Saturday(5). Despite the disparagement, Elvis finds refuge in his physical transformation into the King of Rock.Make-up is a tool to success, metaphorically providing him with the opportunity to escape his menial reality. In this way, Elviss physical mask is similar to Tsotsis emotional shield. Real make-up, however, is seen as a dangerous option(11) because he could be mistaken for a cross-dressing prostitute(11). Elvis resorts to layers of talcum powder powder and is dissatisfied(11) with his end result. The conservative Nigerian culture deni es him freedom in expressing his genuine love for music and dance, and Elvis becomes afraid to define his impersonation as anything other than a materialistic occupation. His mother whitethorn have given him a name that carried her artistic inspiration, but she failed to raise him into a life where his true character could flourish without her. It takes Tsotsi years to accept his name, and Elvis a lifetime to try to live up to his.Together, film and novel act as a microcosm for urban African society-a culture in which names are carefully chosen as a representation of character. Hood and Abani use Tsotsi and Elvis to comprise the powerful role of names in influencing and molding developing characters. Author and director stress the indigence to take control and establish ourselves in a way that brings honor to our names, and that doesnt allow societys pre-prescribed connotations to define us.

Schools Killing Creativity Essay Example for Free
Schools cleansing Creativity EssayIn this TED talk segment by Ken Robinson, an English born prof explains why the educational system in the U.S. is remaining stagnant and unfulfilling to bookmans needs. Robinson begins his arguments by stating, The educational system of the linked States has been accompanied by the same curriculum for the past 125 years. Schools be unknowingly bend creative minds into memorizing machines to meet the criteria of acceptance for colleges across the nation. The educational system has labeled failure as unjustifiable in return generations of children bring afraid to take a risk. Robinson implies, Failure is essential to success, when a scholar looks at failure as no option, they neglect their ability to grow and think for themselves. In some parts of the nation, high school drop outs exceed the number of graduates by a 60% margin. Robinson also states that, the period educational system is robbing schoolchilds of the creative minds we argo n all born with. Research proves your brains imaginative and creative lobes atomic number 18 most active during childhood years. Replacing this creativity with measuringization, results in a disengaged classroom. regularize testing produces a false evaluation of a childs capabilities, only basing statistics on the encumbrance subjects of math, science, and literacy.The average high school dropout rate in the United States remains a staggering 60% in the majority population. Within minority populations as much of 80% of students will fail to mother a high school diploma. Unaccounted for in these statistics are students who are disengaged in the classroom, and will get postcode out of it. America stands as a global leader in m peerlessy spent on education, yet we are displacing this investment of would-be graduates within our economy, to even more m superstary spent on repairing the result of a dropout generation. An estimated one trillion dollars of revenue within our economy c ould be salvaged if we could take the across the nation 60% and reduce this number to 30%.Professor Robinson touches on the fact that we as humans are instinctively creative. Creativity is essential for a child to achieve something that isnew, distinct, and imaginative. Education professionals are existence pressure to follow specific guidelines of standard testing, resulting in a conclusion of what a child is capable of conformist to. Without a broad spectrum of testing we are limiting the student to his or her adaptability rather than what they naturally outperform at. Good teaching habits, such as engaging students to think for themselves and motivating them to be creative, are beingness jeopardized by core curriculum. Robinson refers to education as a result of learning. Educating the students on how to learn, creates any environment the student is capable of thriving in. The system is lacking a variety of studies that engage creativity. Subjects such as the arts, humanitie s, friendly sciences and even things such as dance are not being recognized as crucial to a well rounded education.Studies show overall test scores are substantially land in schools that lack a variety of exploratory classes. Robinson argues, to fully understand math science and literacy, one must explore a diverse culture of learning. Without a variety of knowledge and creativity the learning taught in these core classes becomes meaningless. The subjects focused on by standard testing cannot be accurately measured as a generalization of a childs capabilities. He tells a figment of girl who couldnt focus in school. She was unable to sit still long enough to do any work she was being assigned. This behavior resulted in her being clinically classified as wo(e) from ADHD. While doing homework alone one afternoon, her parents examined her behavior unknowingly to her. After just minutes of session at her desk she would get up and begin to move around in a dancing fashion. Her pare nts wherefore realized that there was nothing wrong with her at all, she was meant to be a dancer. She went on to have one of the most successful dance careers of her generation. Robinson reinforces this story with the notion that all of us are created differently with laughable talents here stands the flaw of standardization. In all of the worlds greatest educational systems, there are similarities within the education culture that America has lacked. In these countries educators are being held to a higher standard and looked at as an investment. Here in the United States teachers are often looked at as a transportation of information.Throughout countries that thrive in education, it is realized that students are only as good as the teachers. Teaching curriculum is acknowledged at the school level where learning is actually taking home incomparison to state and government regulated districts, which are essentially disengaged with what is going on inner(a) the classroom here in the US. Without the pressure to meet the demands of a set curriculum, students are able to become engaged in interests and talents individually. Throughout the entire lecture, Robinson invokes the point that Americas educational system is in need of reform. Our system of testing should accompany an overall goal of learning and not be held as primary assure of a students potential. There are many variables that accompany a students capabilities besides what is being focused on as a means of evaluation. The standard testing should be held as partial review of capabilities, not as an entirety. Subjects that individual students find spark their interests are being deemed unimportant, leaving the student to feel as though they are incapable of success.Courses that students find passion in will create a sense of curiosity in learning. When the light of curiosity becomes a students motivation is when true self learning takes place. The tragedy is that more than 60% of Americans drop out o f high school feeling that they are unable to meet the requirements of life. Robinson makes clear of the fact, Not any-one human is build the same we are a world full of individuals. School systems should give students the tools necessary to find what they are best at and pursue those areas they excel in. The lecture is ended by a request that we climb up changing the way we approach education. Begin to put learning before standards with this movement we can hit into brilliant minds that otherwise would be ignored. Once this movement has begun we can in turn, start a revolution. kit and boodle CitedRobinson, Ken. Ted Talks.Ken Robinson How to Escape Educations Death Valley.YouTube. YouTube, 10 May 2013.

Women in Tennysonââ¬Ã¢¢s Poems Essay Example for Free
Wo workforce in Tennysons Poems EssayIn The Lady of Shallot Tennyson portrays the lady as somewhat of a victim by being trap in her room weaving as if she leaves she will break an elusive curse she is under. In form 63 we see that she hath no loyal knight and true this implies to us that she is utterly alone in her world and whether she stays or leaves men have set up a world she is unsaved to fail by growing old alone or by dying. We go by the rime thinking that she is content with living in solitude looking out at the world by her mirror but when Sir Lancelot suddenly appears in Part 3 we see her look out the windowpane and break the curse, this shows that Lancelot ultimately brought her to her death. But this point can be contradicted by the point that Sir Lancelot did non until now know he was being watched and you could argue that her cause female weakness of sexuality led her to her own death. Following on the point that she is not entirely a victim it is shown i n the cables lengths she left the weave she left the loomTennysons repetition of the world left emphasizes the gravity of her actions and the fact that she has been trapped in the tower all her life and is now leaving implies a whizz of freedom, this is also shown in the line she loosened the chain Tennyson could be symbolising the fact she is breaking free from the constraints of a male dominate world. On the other hand we again come to feel pity for the lady at the land up of the poem due to the males and Lancelots curt attitude to her body and Lancelots comment that she has a beauteous face which suggest that the male world is ignorant and conceited. In Godiva we are first introduced by Tennyson to Godiva as being part of a legend this is then wildly contradicted when we get our first glimpse of Godiva as she is seen as being controlled by her husband the grim earl and is just a possession towards him which institutionalizes us the sense that this is in fact a male dominat ed world this is further shown when the Earl patronises Godiva by saying you would not let your little finger ache.But when we get to stanza 4 we see it is a somewhat transformative stanza as Godiva shekelss to break away from her husbands constraints, this is evident in the line unclasped the wedded eagles of her belt we start to see her transform into a strong, independent woman. Yet we still see that although she is defying her husband and ridingthrough town she is still made to feel extremely uncomfortable and still violated by men when she is looked at by a peeping tom this shows although she is doing a magnificent act of defiance she is still degraded by men. On the other hand this is contradicted by the peeping tom being instantly blinded. Tennyson has used Lines much(prenominal) as like a creeping sunbeam and like a summer moon to whitethornhap symbolise the fact that Godiva has huge power and capability such as the sun and moons ability to give out and create light inste ad of loathsomenessness. This could also signify the fact that Godiva is ending a dark time of high taxes.The last lines of the stanza express that she took the tax away and built herself an everlasting name. Tennyson uses the pronoun she to emphasize the fact that it was Godiva who took away the taxes and not the earl. Therefore showing how she is ultimately stronger than the grim earl. In conclusion some may agree with the fact that although in most of Tennysons poems he is describing predominately male worlds and the women are presented as victims, In Godiva and the Lady Of Shallot the main characters are women who appear victims in the beginning but then ultimately break out of their confinement as inferior people and become women who make their own resource and decide how their own lives are going to go for the first time, therefore I believe they peradventure are victims in some ways but the ways in which they are not rout them.

Googles Methods of Motivating Employees Essay Example for Free
Googles Methods of motivate Employees EssayWhat is life like at Google? After extensive research I found a wide variety of opinions about life at Google. Googles website portrays Google as the best of all places to work. They furnish many luxuries including on site massages and health clubs in addition to free dining and vending options. The guidance style of Google is very lackadaisical and far from serious. Their motto is search, search, and search. Googleplex located out of San Jose, California has a anomalous method of motivating employees vastly different from other corporate America companies. New hires ar dumbstricken by Googles reputation.If they pass the unorganized and exhausting interview process, they will be able to engage the extravagant perks that attract many to Google initially. Googles goal is to keep employees focused on work by eliminating anything that might interfere with production. Current employees make use of this concept depending on their lengt h of employment with the company. Ex-employees fool a different view of Googles culture and the driving forces that power it. Many of Googles archaic employees determine this atmosphere leads to 24/7 working days with no personal time.They feel overworked and underpaid with undersize advancement opportunities available. With that being say, my assessment of the working environment at Google is similar to that of former employees. I feel Google is mirroring the college environment by meeting the basic needs of their employees. By making the basic needs readily available within the working environment, they eliminate outside distractions thus hoping to increase production. However, I feel this philosophy is comparable to that of many cults.They entice employees with so-called spectacular benefits and average pay all the while neglecting to secure them how demanding the working environment is at Google. I am surprised that Google does not offer on-site life sentence arrangemen ts too. Robbins and Coulter (2009) state, Google has been named the best company to work for by Fortune magazine two years running. I pay no doubts they are not a fantastic company to call home, but they are not retaining life time employees. At some point these associates are losing motivation and decide to side for better opportunities.These situations tell me that Google is failing their employees at some point. I believe the break-down begins at the top of the organisational structure within Google. They emphasize their benefits but neglect to explain employee expectations or job demands to their staff. After the penchant phase, employees get the real taste of Google little time for the perks, exhausting hours, unorganized working environments, lacking instruction guidance, little advancement opportunities, minimal pay and a child-like atmosphere. This is the perfect recipe for burnout.Sequentially burnout creates Googles biggest challenge. It has been said that middle mana gement at Google might oversee over 100 people at one and only(a) time. How can this be effective? Management needs to be involved and become more hand on with their employees. They could start with career plans, training and promotable reviews. Also, I feel Google should balance their perks by offering less(prenominal) on-site and more down time or empathy to their associates on a personal level. The perks offered are large(p) but they are missing the most important factor-a sincere personal touch.If I were managing a police squad of Google employees I would try to implement a hands on type of approach. I would set up monthly meetings and give my staff appropriate feedback to help them grow and excel. A rewards and recognition program would be beneficial to them as well as a career plan. It would also be helpful to have training sessions when needed. Lastly, I would empathize with my employees by stressing balance between family and working time. Google has a nice chopine howev er, I feel these few changes could be vital assets to enhancing their working place while keep long term associates.
Supply and Demand Simulation Essay Example for Free
Supply and pauperization Simulation EssaySupply and make is the common sense principle which defines the generally observed relationship between demand, fork up and harms as demand increases the price goes up which attracts new suppliers who increase the supply speech the price back to normal (Law of Supply and Demand, 2010). A surplus in the market exerts a down(prenominal) mechanical press on price eyepatch a shortage in the market exerts an upward pressure on price. In the supply and demand computer simulation Goodlife has control of the apartment rental community is Atlantis. In the first year Goodlife wants to bring down the vacancy ordinate to about 15 percent while maximizing revenue. Goodlife must lower the make up of rent in order to lower the vacancy rate but they have to make sure they dont lower it too much or they go out decrease their revenue so they must find at what rental rate they will lower vacancy but no lose revenue. As the years go by several(pren ominal) things affect the supply and demand of the Goodlife Company, population increase, individuals wanting long-term housing and a price ceiling.Shifts in supply and demand affect decision making by causing the caller-out to look at how to get the greatest revenue with the changes. The supply and demand simulation went over several key points that were alike part of our textbook reading such as total revenue and demand, individual and market demand, bulls eye price elasticity and shifting supply and demand. Total revenue and demand is the ability for a company to tell whether the total revenue will go up or down when they raise or lower their prices (Colander, 2008).Individual and market demand refers to how individuals may stop buying a product imputable to a slight rise in cost, the market demand is influenced both by how many great deal drop out totally and by how much an existing consumer marginally changes his or her quantity demanded (Colander, 2008). pass across price elasticity of demand is when the price of a product goes up and it positively impacts the demand of another(prenominal) product. Shifting supply and demand is the ability of the company to shift supply to meet demand and hold up equilibrium.At Regence BlueCross BlueShield supply and demand affects the cost of premiums as well as the type of benefits addressable on plans. It is important in healthcare to figure out which benefits are sought after and what it will cost to cover those benefits, by slimming down on the benefits that are used less then they can win benefits that individuals want at a lower cost than if they supply all benefits. One example of this is position limitations of such benefits as chiropractic or physical therapy while increasing the benefits for preventive care.Price elasticity of demand affects the decision making of the consumer and of the organization by changing the amount of a product available as well as the price of the product. Consumers will swit ch products if they are unable to find the product slow or if the price is higher than a similar product. Organizations must continue to shift the supply and price of a product in order to stay competitive and still make revenue.In the simulation I learned how to maintain equilibrium with supply, demand and price while maintaining company revenue at the highest rate. Goodlife must keep changing the availability and price of the apartments in order to keep up with supply and demand and maintain revenue, one way they did this is by turning some of their apartments into condos this decreased the number of apartments available but brought in revenue in a different manner.

Vehicle ad-hoc Network (VANETS) Technology
fomite ad-hoc Network (VANETS) TechnologyChapter 1IntroductionNow a day, e actuallything is sorrowful away from wired engine room and take uping towards piano tuner. The fascination of mobility, accessibility and flexibility halts radio technologies the dominant mode of transferring all sorts of entropy. Satellite televisions, cellular ph hotshots and wireless Internet be well-known operations of wireless technologies. This work presents a promising wireless use and introduces a tiny contri stillion to its research community.Research in wireless talk field is growing faster, day by day, and so any early(a) field. It serves a rattling b street range or series of diverse kind of applications utilise different topologies. Every genius of these comes with roughly modernistic and specialized protocols. In this research, we will present an introduction to a wireless technology. This wireless technology directly affects car accidents and the sales of mavin of the ov ersizedst commercialises. It is the technology of building a strong net income in the midst of mobile fomites i.e. let fomites communicate to each different. This promising technology is literally called Vehicular Ad-Hoc Networks (VANETs).1.1 soilSince the outgrowth invention of mobile fomites, governments and manufacturers turn over researched accidents to cut back the number of vehicle crashes in order to reduce costs, injuries and fatalities. First of all, VANET technology is going to reduce crashes by doing research in this field. Accordingly, related to governmental regimen initiated new projects to the learning institute for study, research, development in the field of wireless technology and VANETs also paying attention in its standards. The Dedicated brusk ramble Communications (DSRC) 1 is a pioneer ITS (Intelligent Transportation Systems which is a branch of the U.S. Department of Transportation 2) project dedicated to VANET standardization. Then, the acronym or short form DSRC becomes a spherical or familiar name of kind of standards that aim to put VANET technology into life. The DSRC mainly concerns with the intercourse that is how to make different communication links between vehicle-to-vehicle and vehicle-to/from- streetside units.1.2 MotivationIn the closing curtain few years, vehicular communicate has gained great attention in industry. Federal communication commission (FCC) has assigned 5.850-5.925GHZ frequency band to get along safe and efficient itinerary trips, which is planned for vehicle-to-vehicle and vehicle-to-infrastructure communication. Car manufacturers, e.g., Audi, BMW and DaimlerChrysler, also formed a Car2Car communication syndicate 3, in which the prototype development for inter-vehicle communications is underway.In near past, IEEE 802.11-based solutions for VANETs are also studied by IEEE 802.11p. IEEE 802.11p Wireless recover in the Vehicular Environment ( wrap) that defines turns to IEEE 802.11 to he lp Intelligent Transportation Systems (ITS) applications. IEEE 802.11p helps selective information exchanges between fast moving vehicles with each opposite and also exchanges information from vehicles to highway side unit or from road side unit to vehicles in the licensed ITS band of 5.9 GHz. The Dedicated Short-Range Communications (DSRC) at 5.9 GHz is here today to provide rubber eraser that is increasing safeguard in case of road accidents, reducing highway or road maintenance cost and also improving mobility. Inter second geartion and road departure collisions report for round about 50 percent of all crashes and victims on our roads. On an honest day in the United States, vehicular collisions kill 116 and injure 79008. More health care dollars are consumed in the United States treating crash victims than any some other cause of illness or injury 8, 10 the placement in the atomic number 63an Union is similar, with over 100 deaths and 4600 injuries daily, and the annual c ost of 160 billion 11. By getting rid from road victims and crashes, DSRC elicit provide or play important role in reducing road accidents, deaths, injuries, heavy traffic and increasing road safety by improving communication between vehicles and between vehicles and road side infrastructure. DSRC emerged from a partnership among automobile manufacturers, state and federal pane officials, toll transponder equipment suppliers and the Federal Communications Commission. There is a recognized need for on-the-go communication with motor vehicles and safe communication between vehicles to increment highway safety by providing prototypes and alerts that enable drivers to take corrective and/or evasive actions. At the same cartridge holder, it outhouse be able to provide information i.e. real time information to drivers so that to improve mobility and motorist convenience, such as information on congestion or traffic incidents. The car manufacturing industrys determination to roll o ut vehicle-to-vehicle communication in the near future and, on the other hand, to the increasing disillusionment concerning the need for the vast number of protocols developed for general Mobile Ad-Hoc Networks (MANETs) in the past few years while on the other side that is for VANETs, industry pressure has created a situation in which an overwhelming interest in solutions to problems leads to a preference for real-world research as strange to fancy theory. As the concept came from MANETs which totally depend on the subscribers motion as the motion is random it is difficult to cater it but this problem was very negligible when researchers observed it in VANETS. At highways vehicle move in an organized pattern with different revives so initially it seemed that VANET will easily be implemented. some other major reason for VANET fire be Traffic deaths and injuries which is a major health and mixer issue. While industrialized nations (e.g., the United States) have continuously reduc ed annual traffic deaths since 1970, annual traffic-related fatalities and injuries continue high (in the United States alone there were over 41,000 deaths and 5 million injuries in 2000, according to the NHTSA) 7. The sparing impact of vehicle crashes in the United States exceeded US$230 billion or 2.3 percent of the U.S. GDP in 2000 7. We want to remain connected with the world through net whether at home, airport, at work or even on the roads.ExampleDescriptionObstacle warningStopped/Skidding/Slowing down vehicle warning, road obstacle/object-on-road warning lane Merge/Lane replace AssistanceMerging/Lane changing vehicles communicates with vehicles in lane to safely and smoothly merge.Adaptive Cruise/ accommodative Driving automatically stop and go smoothly, when vehicles are in heavy roadway traffic cooperates driving by exchanging cruising data among vehicles.Intersection/Hidden Driveway Collision Warningvehicles communicates to avoid collisions at intersections without traf fic lights or hush-hush driveway.Roadway Condition Awareness vehicles communicates to extend vision beyond line of sight (e.g. beyond a big turn or over a hill)Table-1.1 Example of Vehicle Safety Communication 101.3 kitchen stove of ProjectSome of the industries and universities working on VANETs are as followDaimlerChrysler AGFraunhofer FOKUSNEC Europe Ltd.Robert Bosch GmbHSiemens AGTEMIC TelefunkenMicroelectronic GmbHUniversities of Mannheim, Hamburg-Harburg, Karlsruhe, and Hannover.1.4 Organization of ProjectThisthesisis mainly divided into four chapters. In the first two chapters (1-2) introduction and an overview over the topic and used technologies is given. In the following chapter (3), we have discussed the standards of IEEE and also discussed the mack Layer and PHY Layer of IEEE 802.11 in detail. In chapter 4, simulation analysis of our work is shown along with the results. In the last chapter, we have reiterated this whole thesis, what we have concluded from this proje ct and future work needs to be do are discussed. Finally, in appendix some additional information can be found. In chapter two, VANETs characteristics, some of its applications and the research challenges faced by governments and car manufactures are discussed, continued by mac Layer and PHY in chapter three. We have also discussed the stray architecture in chapter 2. From chapter three on, we have a look at some protocol improvements and extensions. Some thoughts, tests and their results on VANETs, those are related to our work, can be found in chapter 4.Chapter 2VANETsVANETs (Vehicle ad-hoc Networks) is a form of Mobile Ad-hoc Networks (MANETs), which provide a communication between the vehicles and also firm equipments, usually defined as road side equipments.2.1 What is VANETVehicle ad hoc vane comprises of three words.i. Vehicleii. Ad-hociii. Networksi. VehicleA machine such as a bus or car for transporting commonwealth or uprights. 4A lot of progress is happening in the field of vehicles since the invention of wheel. Development is collect to provide services to the people and make their task easier.ii. Ad-hocIt refers to dealing with special situations as they occur or else than functions that are repeated on a regular basis. For example you just meet someone remote your office and you exchange some words. On the other hand infrastructure organisation is a formation which is fully installed and deployed than it works according to some predefined rules and regulations.iii. NetworkA system, as in a parentage or university, consisting of a computer or computers and connected terminals, printers etc. specific, a local area earnings.3The concept of interlocking is introduced because resources are peculiar(a) and we have to implement them efficiently. As it is not possible for firms to provide printer, faxes and other machines to everyone so they just inter linked all the devices so that each one can utilize it keeping the cost at negligible. Vehicular connectivity can be fairly considered a future grampus application, adding extra value to the car industry and operators services. Taking into account the constant growth of automotive market and the increasing demand for the car safety, also driven by regulatory (governmental) domain, the potential of car-to-car connectivity is immense. Such system should be suitable for a wide spectrum of applications, including safety related, traffic and fleet control and entertainment. First, issues concerning architecture, protective cover, routing, performance or QoS need to be investigated. Standardization of port wines and protocols should be carefully planned to tick off interoperability, as vehicles coming from different vendors must communicate seamlessly. Having different competing systems would result in decreased market penetration and poor overall system efficiency, thus further one common system can be deployed. And finally, wise deployment scheme has to be proposed , as most(prenominal) application would become functional except after certain market penetration is reached. The first milestone of standardization process was the al post of 75 MHz of DSRC (Dedicated Short Range Communications) spectrum to accommodate Vehicle-to-Vehicle (V2V) and Vehicle-to- Infrastructure (V2I) communication for safety-related applications by US Federal Communications Commission (1999). commercialized applications are also allowed to operate in this spectrum.2.2 VANETs ApplicationsAccording to the DSRC, there are over one coulomb recommended applications of VANETs. These applications are of two categories, safety and non-safety related application. Moreover, they can be categorized into OBU-to-OBU or OBU-to-RSU applications. Some of these applications are as followed2.2.1 Co-operative Collision WarningCo-operative collision warning is an OBU-to-OBU safety application, that is, in case of any disconnected change in speed or driving tutelage, the vehicle is c onsidered abnormal and mobilizes a warning inwardness to warn all of the following vehicles of the likely danger. This application requires an efficient broadcasting algorithm with a very bitty latency.2.2.2 Lane Change WarningLane-change warning is an OBU-to-OBU safety application, that is, a vehicle driver can warn other vehicles of his intention to change the traveling lane and to book an empty room in the approaching lane. Again, this application depends on broadcasting.2.2.3 Intersection Collision WarningIntersection collision warning is an OBU-to-RSU safety application. At intersections, a centralized node warns approaching vehicles of possible accidents and assists them determining the suitable approaching speed. This application uses only broadcast messages. In June 2007, General Motors GM addressed the previously mentioned applications and announced for the first wireless automated collision avoidance system using vehicle-to-vehicle communication (Figure-2.1), as quote d from GM, If the driver doesnt respond to the alerts, the vehicle can bring itself to a safe stop by avoiding a collision.2.2.4 Approaching Emergency vehicleApproaching emergency vehicle is an OBU-to-OBU public-safety application, that is, high-speed emergency vehicles (ambulance or police car) can warn other vehicles to clear their lane. Again, this application depends on broadcasting.2.2.5 Rollover WarningRollover warning is an OBU-to-RSU safety application. A RSU localized at hypercritical curves can broadcast information about curve angle and road condition, so that, approaching vehicles can determine the maximum possible approaching speed before rollover.2.2.6 hold out Zone WarningWork zone warning is an OBU-to-RSU safety application. A RSU is mounted in work zones to warn incoming vehicles of the probable danger and warn them to decrease the speed and change the driving lane.2.2.7 Near bourne 5Traffic forecast Violation WarningCurve Speed WarningEmergency Electronic brak e Lights2.2.8 Mid Term 5Pre-Crash WarningCooperative Forward Collision WarningLeft Turn AssistantLane Change WarningStop Sign Movement AssistanceApplicationComm. typeFreqLatencyData genicRangeTraffic Signal Violation12V One-way, P2M10 Hz100msecSignal Status, Timing, Surface Heading, Light Position, conditions250mCurve Speed Warning12V One-way, P2M1 Hz1000msecCurve Location, Curvature, Speed Limit, Bank, Surface200mEmergency Brake LightVehicle to Vehicle Two-way, P2M10 Hz100msecPosition, Deceleration Heading, Velocity200mPre-Crash SensingVehicle to Vehicle Two-way, P2P50 Hz20msecVehicle type, Yaw Rate, Position Heading, Acceleration,50mCollision WarningVehicle to Vehicle One-way, P2M10 Hz100msecVehicle type, Position, Heading Velocity, Acceleration, Yaw Rate150mLeft Turn Assist12V and V21 One-way, P2M10 Hz100msecSignal Status, Timing, Position, Direction, Road Geom., Vehicle Heading300mLane Change WarningVehicle to Vehicle One-way, P2M10 Hz100msecPosition, Heading, Velocity, Acceler ation, Turn Signal Status150mStop Sign Assist12V and V21 One-way10 Hz100msecPosition, Velocity, Heading, Warning300mTable-2.1 Eight high- frontity vehicular safety applications as chosen by NHTSA and VSCC. Note that communication freq. ranges from 1-50 Hz and Max. Communication range spam 50-300 meters. P2M represents Point-to-Multipoint, 12V represents infrastructure to vehicle and V21 represents Vehicle-to-Infrastructure. 52.2.9 Comfort related applicationsTraffic efficiency bankrupt navigationInternet accessThe whole theme of these applications is improving passengers comfort and traffic efficiency. That includes nearest POI (Points of Interest) localization, up-to-the-minute traffic or weather information and interactive communication. All kinds of applications might be applied here. Another application is reception of data from commercial vehicles and roadside infrastructure about their businesses (wireless advertising). Enterprises (shopping malls, fast foods, gas stations, h otels) can hatful up stationary gateways to circularize marketing data to potential customers passing by.The important deliver of comfort/commercial applications is that they should not interfere with safety applications. In this context traffic prioritizing and use of crystallise physical im part is a viable solution.2.2.10 Safety related applicationsAccidence avoidingDanger warningsIntersection coordinationCooperative drivingSafety-related applications may be grouped in three main classes assistance (navigation, cooperative collision avoidance, and lane-changing), information (speed limit or work zone info) and warning (post crash, obstacle or road condition warnings). They usually demand direct communication due to their delay-critical nature. One such application would be emergency notifications, e.g. emergency braking alarms. In case of an accident or sudden hard breaking, a warning is sent to the subsequent cars. That information could also be propagated by cars driving in the opposite direction and, thereby, conveyed to the vehicles that might run into the accident. Another, more advanced example is cooperative driver assistance system, which exploits the exchange of sensing element data or other status information among cars. The basic idea is to broaden the range of learning of the driver beyond his field of vision and further on to assist the driver with assistance applications. communicate this data to cars following on the same road, drivers get information about hazards, obstacles or traffic advert ahead hence driving is more efficient and safer. Some applications of this kind are in operation(p) only when certain penetration of VANET enabled cars is reached. 62.3 VANETs CharacteristicsAlthough VANETs, Wireless Sensor Networks and Wireless Mesh Networks are special cases of the general MANETs, VANETs stimulate some noticeable characteristics that make its nature a unique one. These properties present considerable challenges and requir e a laid of new especially designed protocols.Due to the high mobility of vehicles, that can be up to one hundred fifty kilometers per hour, the topology of several VANET changes frequently and unexpectedly. Hence, the time that a communication link exists between two vehicles is very short especially when the vehicles are traveling in opposite directions. A one solution to increase the lifetime of links is to increase the contagion power, but increasing a vehicles transmission range will increase the collision probability and mortify the overall throughput of the system. The other solution having a set of new protocols is employing a very low latency.Another effect of these high speed nodes is that the good of the broadcasted messages is very critical to latency. For example, if we assume that a vehicle is unexpectedly stopping or suddenly stops, it should broadcast a message to warn other vehicles of the probable danger. Considering that the driver needs at least 0.70 to 0.75 se c to initiate his response 7, the warning message should be delivered at virtually zero sec latency.In VANETs, location of nodes changes very quickly and unpredictably, so that, building an efficient routing table or a run of inhabit nodes will tire out the wireless channel and reduce the network efficiency. Protocols that rely on prior information about location of nodes are likely to have a poor performance.However, the topologies of a VANET can be a benefit because vehicles are not expected to leave the covered road therefore, the running direction of vehicles is predictable to some extent.Although, the design challenge of protocols in wireless sensor networks is to besmirch the power inlet, this is not a problem in VANETs. Nodes in VANETs depend on a good power supply (e.g. vehicle battery and the dynamo) and the required transmission power is small compared with power consumption of on-board facilities (e.g. air-condition).It is predicted that, as VANET is deployed in the b eginning, only a small percentage of vehicles will be outfitted with transceivers. Thus, the benefits of the new technology, especially OBU-to-OBU applications, will not go up until many years. Furthermore, the limited number of vehicles with transceivers will lead to a numerous fragmentation of the network. Even when VANET is fully deployed, fragmentation may still exist in rural areas, thereupon, any VANET protocol should expect a fragmented network.Privacy, safety and security are of thoroughgoing effect on the public receiving of this technology. In VANETs, every node represents a specific person and its location tells about his location.Any requirement of privacy can ease a third party monitor persons daily activities. However, from the other point of view, higher authorities should gain access to identity information to ensure punishment of illegal actions, where, there is a fear of a possible misuse of this feature. The tampering with messages could increase false alarms and accidents in some situations defeating the whole purpose of this technology.Finally, the key difference between VANET protocols and any other form of Ad-Hoc networks is the design requirement. In VANETs, the key design requirement is to minimize latency with no prior topology information. However, the key design requirement of Wireless Sensor Network is to maintain network connectivity with the minimum power consumption and the key proposed design requirement of Wireless Mesh Network is reliableness.WE can summarize the main characteristics of VANETs as followsHigh mobility of nodesNo prior information about the exact location of neighbor nodesPredictable topology (to some extent)Significant latency requirement especially in cases of safety related applicationsNo problem with powerSlow migration rateHigh possibility to be fragmented important effect of security and privacy2.4 Research Challenges in VANETsWhen deploying of a vehicular networking system, a number of issues have to be determined, often from distant fields of expertise, ranging from applications improvement up to efficient issues. VANET could be considered as an instantiation of MANETs (Mobile Ad hoc Networks) however their behavior is fundamentally different. These unique characteristics of these networks are as followsRapid topology changes and fragmentation, resulting in small effective network diameterVirtually no power constrainsVariable, highly dynamic scale and network densityDriver might adjust his behavior reacting to the data received from the network, inflicting a topology changeHere we briefly mention some of the core research challenges that need to be discussed.2.5 Wireless Access technologyThere are several wireless access standards that could be used as a foundation for VANET technology. In general the major seek is to provide a set of air interface protocols and parameters for high-speed vehicular communication by mean of one or more different media.2.5.1 cellular technology (2/2 .5/3G)The key role of 2/2.5G i.e. cellular technology are coverage and security, and 3G, slowly but steadily coming over 2/2,5G, provides enhanced and better capacity and bandwidth. Several telematic and fleet heed projects already uses cellular technology (e.g. SMS reports), on the other hand it is comparatively more expensive, together with limited bandwidth and latency make it impossible to use as a main communication means.2.5.2 IEEE 802.11p based technologyIEEE is working on a variation of 802.11 standards that would be applied to support communication between vehicles and the roadside, or, alternatively, among vehicles themselves, operating at speeds up to 200 km/h, handling communication ranges as high as 1,000 meters. PHY and MAC layers are based on IEEE 802.11a, shifted to the 5.9 GHz band (5.850-5.925 GHz within US). The technology is promoted by the car industry both in Europe and US. Estimated deployment cost is foreseen to be relatively low due to large production volu mes. C. Combined wireless access one of the most significant and important efforts in corporate trust those wireless access technologies is done by ISO TC 204 WG16. It builds on the top of IEEE 802.11p, using additional set of interface protocols. Currently supported standards include Cellular Systems GSM/GPRS (2/2.5G) and UMTS (3G), Infrared Communication and wireless systems in 60 GHz band. Using all those interfaces in a single, uniform system would result in increase flexibility and redundancy, thus improving applications performance. Apart from interoperability issues, CALM is also engaged in the standardization of the protocols, network layer and the management services.2.6 WAVE ArchitectureWAVE system architecture is totally a set of WAVE standards that describes the communication stack of vehicular nodes and the physical air link between them. Any RSU may have two interfaces, one for the WAVE stack or architecture or wireless networks and the other for external interfaces li ke wired line Ethernet that may be used to get access to internet and for connection to internet it is mainly used. Similarly, each OBU may have two interfaces, one for the wireless WAVE stack and the other for sensor-connections and human interaction.OBU is not full-duplex so, therefore, it cannot transmit messages simultaneously, so DSRC is half-duplex. The RSU and OBU can send messages only when the channel becomes idle and also confirmed that it is idle. If the channel is busy, RSU and OBU need to wait and if the channel is idle then RSU or OBU will send the signal Request to Send (RTS) to control channel. The control channel will share the channel on the basis of high antecedence first followed by low priority. The high priority messages are those messages related to public safety.The WAVE architecture is defined by the IEEE 1609 family of standards and uses the IEEE 802.11p amendment to extend the use of 802.11 to vehicles. The IEEE 1609 family is undisturbed of four stand ards describing the resource manager, security services, networking services and multi- channel operations.WAVE standard consists of five complementary parts802.11p Wireless Access in Vehicular Environments (WAVE) 8 which is an amendment to the well known IEEE 802.11 Wireless LAN Standard and covers the physical layer of the system.1609.1 imaging manager 8 that covers optional recommendations for the application layer. 13, 141609.2 Security Services for Applications and Management Messages 8 that covers security, secure message formatting, processing and exchange. 13, 141609.3 Networking Services 8 that covers the WAVE communication stack. 13, 141609.4 Multi-Channel Operation 8 that covers the arrangement of multiple channels and how they should be used. 13, 14The most evident part is its dual stack. Whereas there is a well-known stack, called TCP/IP stacks and on the other hand there is a stack, called WAVE Short Message stack. The function of the WAVE Short Message stack is to p rovide a connectionless transport protocol i.e. without checking the connection that whether connection is made or not, similar to UDP but on a single-hop basis. The safety applications are supposed to use this stack only while non-safety applications can use both. It should be noted that the devise or design of this approach is cogitate on non-safety applications and considers safety as a black box.2.6.1 IEEE 1609.1 Resource ManagerThe IEEE 1609.1 standard defines the architecture and data flows of WAVE. It also describes command messages and data formats. 9, 8. The standard explains how data communication between road side units and vehicle on board units occurs. The discussion of this standards operation will be based on the standard defines applications residing on the on board unit as Resource Command Processors and those residing in road side units or elsewhere as Resource Manager Applications. The Resource Manager is the focus of this standard and is also the application th at is responsible for managing communication between multiple Resource Manager Applications and Resource Command Processors. 9, 8WAVE communication imitates a client- legion architecture that is managed by the Resource Manager. For example, in the case where a company wants to provide traffic updates by analyzing vehicle speed statistics in a stretch of highway, the application that analyzes the traffic data (a Resource Manager Application) would reside on the road side unit or a remote server that is connected to a road side unit. When the Resource Manager Application sends a request for the speed of the vehicle the Resource Manager application in the road side unit receives the request then forwards it to the vehicles Resource Command Processor application using WAVE. The vehicle then replies to the Resource Manager which forwards the message to the Resource Manager Application. If another passing vehicle asks for traffic updates by displace a request to the road side unit, the r oles of client and server from the previous case are switched.WAVE is designed to provide secure communications and minimize the cost of on board units by minimizing the join of processing required by them. All only desired information relevant to road safety will be transferred.2.6.2 IEEE 1609.2 Security ServicesThe IEEE 1609.2 standard defines secure message formats and processing and infers circumstances for using secure message exchange. 13, 8. It deals with security services for applications and management messages. Security is important in WAVE because vehicles transmit sensitive information that could constitute a violation of privacy if accessed by unauthorized parties. The efficacy and reliability of a system where information is gathered and shared among autonomous entities raises concerns about the authenticity of the received data. For example, a bad actor could misrepresent its observations in order to gain advantage (e.g. a vehicle V falsely reports that its desired road R is stopped with traffic, thereby encouraging others to avoid R and providing a less-congested trip for V on R). More malicious actors could impersonate other vehicles or road-side infrastructure in order to trigger safety hazards. Vehicles could reduce this threat by creating networks of trust, and ignoring, or at least distrusting, information from un-trusted senders. 13, 8A trusted communication generally requires two properties are metThe sender is conclusively identified as a trusted source.While in transit, the contents of the senders message are not tampered.WAVE maintains security by ensuring confidentiality and authenticity in message transmissions. The final standard is expected to address privacy issues with the topical version. WAVE ensures confidentiality
