An Efficient Routing Mechanism for Vehicular Ad Hoc Networks

Abstract

Vehicular Ad-hoc Network is a new technology which have become dominant of all the wireless communication with time. It is a group of mobile nodes (vehicles) which forms a infrastructure less temporary network. To route a packet to destination, a node uses intermediate nodes. In VANET, because of frequent topology changes and disconnection of path, it is difficult to provide an efficient protocol. This research work states that, geographical approach routing will have low end to end delay and maximum packet delivery ratio. In this paper we analyze the performance of Greedy Perimeter Stateless Routing Protocol (GPSR) [4] which is a location based protocol and compared it with Ad hoc On Demand Distance Vector Routing protocol (AODV) [3]. To measure and evaluate the parameters NS-2.33 is used as network simulator and Simulation of Urban Mobility (SUMO) as traffic simulator.
