Comparative Performance Exploration of Aodv, Dsdv & Dsr Routing Protocol in Cluster Based Vanet Environment

Vehicular ad-hoc network (VANET) is self-organizing wheeled networks that enable communication in between high speed moving road vehicles like cars, trucks, busses etc. in VANET network each vehicle behave as a mobile node and can be move in any direction with varying speeds that makes highly dynamic environment. The existing mobile ad-hoc network (MANET) routing protocol are unsuitable for VANET because of frequently change in mobility pattern and topology of this network. In last few years many ideas has come and implemented in this area but still there is scope of modernization. The reconstruction of existing protocol or introducing new idea of routing in VANET environment will be a milestone and the performance evaluation will be a nice approach towards that. In this paper we evaluate performance of AODV, DSDV and DSR routing protocol on the basis performance metric packet delivery ratio, end to end delay, and throughput of the network, in the cluster based VANET environment with increasing the number of mobile nodes. The Simulation studies are conducted using NS2.
