Vehicle Collision Avoidance in a VANET environment by data communication

Vehicular Networks ensure the safety of vehicle and passengers by communicating the details about the route. The objective of this article is to make efficient decision making for vehicles to Navigate from source to destination. The RSU (road side units) is assumed to do the manipulation of data received from other RSUs to assist the vehicles in its range. RSU communicates the status of each possible route that a vehicle can enter in order to reach the destination. The data collected from the events that occurred in one RSU range is routed to the RSU that requires that information. The Shortest path routing algorithm for the data communication based on Euclidean distance is employed to disseminate data to the required RSU. The work focusses mainly on how the computing device (RSUs) can process the data and make decisions out of it to the vehicles in its range. Network simulator 2 is used to simulate the scenarios (both vehicles and RSUs are considered as nodes).
