Apply Different Techniques to Face Vehicular Ad-Hoc Network Challenges for Making Secure Systems

In this paper, the concept of VANET is discussed in detail.The different concepts used in VANET are explained with very good style. The applications of VANET are also discussed here. In the near future, most new vehicles will be equipped with short range radios capable of communicating with other vehicles or with highwayinfrastructure at distances of at least one kilometer. The radios will allow new applications that will revolutionize the driving experience, providing everything from instant, localized traffic updates to warning signals when the car ahead abruptly brakes. While resembling traditional sensor and ad hoc networks in some respects, vehicular networks pose a number of unique challenges. The differentchallenges of VANET are explained and explained in detail in this paper.
