Evaluation of packet forwarding of GPSR in VANET

Pooja malhotra

Abstract


Vanet is vehicular adhoc network for communication between moving vehicles and roadside infrastructure. One of the most efficient routing protocol, GPSR is evaluated for packet forwarding approach. As it send data to the node which is closest to the destination node. In this paper we change the transmission range of node and check the performance using metrics parameter packet delivery ratio, loss ratio, end to end delay, routing overhead. And it is found that with increase in transmission range total received Packets, PDR increase which is good. With increase in transmission range Loss ratio decrease and end to end delay remain almost constant.
