Hence, during route discovery phase, it is very important and desirable for the routing algorithm to choose optimal route connecting source and destination, consisting of the most reliable links in the network. Greedy perimeter stateless routing (GPSR) The routing protocol that relies on positions (coordinates)of the nodes and destination address of the packet to make forwarding decisions in multihop wireless networks. We per-form detailed evaluation of the modified routing algorithm. Further we compare the performance of GPSR-R against conventional GPSR protocol and three representatives reliable VANET routing protocols that exist in the literature and establish that GPSR-R provides more improvement in packet delivery ratio and network throughput. The rest of this paper is organized as follows. Section 2describes the related work.
