Comparative Analysis of Dsdv, Dsr, Aodv with Gpsr in Vanet Scenario

VANET is Mobile Adhoc Network in which Vehicles are dynamic in Nature and topology changes frequently. Hence, routing is a big challenge in VANET as Vehicles themselves act as nodes in Network. VANETs have many networking research challenges, and therefore, the design of a protocol with much efficiency is essential . Various protocols have been designed to minimize this challenge. Therefore the performances of Vehicle to Vehicle and Vehicle to roadside communication depend on various protocols. In this paper we present comparative analysis of different Topology based Routing protocols such as AODV, DSDV and DSR with GPSR. The performance of these protocols is examined on the basis of NS-2.35 simulations by using different parameters such as Throughput, PDR, Routing Overhead, End to End Delay and energy for different number of vehicles.
