Collision Avoidance in Ivan to Maintain Inter-vehicular Distance on Highways

In Inter-Vehicular Adhoc Network (IVAN) does not have a fixed network topology but is highly dynamic. The topology of the network changes frequently because wireless links are established and broken down due to certain factors such as the velocity of the vehicles, their mobility patterns and their spatial density. These high dynamics also cause very short times for data transfer. This paper presents Inter Vehicular Collision Avoidance System on Highways to ensure that the vehicles perform safety communication with each other for which can alert the drivers before accidents. This can be done by defining a critical “Inter-Vehicular Distance” to be maintained between and any two vehicles on highways. Moreover, certain vehicles such as ambulance, fire service vans, police patrols need to be given a high priority, as their requirements are crucial during emergency situations. By giving vehicular priorities and providing group communications, our proposed System results vehicular collision avoidance in Inter Vehicular Adhoc Network.
