EFFICIENT ROUTING PROTOCOL WITH COLLISION AVOIDANCE IN VEHICULAR NETWORKS

Abstract

The vehicle-Adhoc Networks are the specific type wireless adhoc networks, framed using the group of vehicles supporting the “on the fly’ communication between vehicles on the roadside. This is basically developed to handle the traffic in an intelligent manner avoiding the unnecessary time elapse, discomfort and the fatalities during the travelling and in turn improvise the convenience in the transportation providing a continuous traffic movement. But certain emergent situations such as the natural disasters, accidents, damaged roads, sudden break down of the vehicles and the appearance of the emergency vehicles disturb the regular traffic flow and safety of the on road vehicles. To ensure the safety of on road vehicles and elude the collision of the vehicles that take place due to improper communications or communication attacks, the paper puts forth an effective routing protocol with collision avoidance, (ERPCA) to identify vehicles with the reliability to transfer information on time and evade the discomforts in travelling. The evaluation of the ERPCA with the network simulator-2 evinces the improvement in the performance of the vehicular-adhoc networks
