Efficient Packet Forwarding Approach in Vehicular Ad Hoc Networks Using EBGR Algorithm
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 (Edge
Node Based Greedy Routing), a reliable greedy position based
routing approach to forward packets to the node present in the
edge of the transmission range of source/forwarding node as
most suitable next hop, with consideration of nodes moving in
the direction of the destination. 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 show that packet delivery ratio is
improved considerably compared to other routing techniques of
VANET.
