Reducing Routing Overhead in Vehicular Ad hoc Networks using EBGR Algorithm

K. Prasanth, Dr.K. Duraiswamy

Abstract


VANETs (Vehicular Ad hoc Networks) are highly mobile wireless ad hoc networks and will play an important role in public safety communications and commercial applications. Routing of data in VANETs is a challenging task due to rapidly changing topology and high speed mobility of vehicles. Conventional routing protocols in MANETs (Mobile Ad hoc Networks) are unable to fully address the unique characteristics in vehicular networks. In this paper, we propose EBGR (Potential Edge Node Based Greedy Routing), a greedy position based routing approach which uses potential score based strategy to forward packets to the node present in the edge of the transmission range of source/forwarding node as most suitable next hop. We propose Revival Mobility model (RMM) to evaluate the performance of our routing technique. This paper presents a detailed description of our approach and simulation results using ns 2.33 shows that routing overhead is reduced considerably compared to other routing techniques of VANET.
