Greedy Perimeter Stateless Routing In Vehicular Ad-Hoc Networks
نویسنده
چکیده
Greedy Perimeter Stateless Routing (GPSR) is a Position-Based Routing Protocol for Wireless Networks that uses the Position of routers. GPSR makes greedy forwarding decision by using closest neighbor’s information of destination. In GPSR each node has the knowledge of its current physical position and also the neighbor node, this knowledge about node provides better routing. When a packet reaches a region where there is no closest node to the destination then greedy forwarding is impossible, the algorithm recover by using perimeter forwarding. By Studying GPSR, we find that Greedy part of GPSR is not always finding the most optimized route. In this paper we investigated about different forwarding method of GPSR in wireless network and also find out the problems and their solutions. The main aim of our study was to identify which routing method has better performance in highly mobile environment of VANET. Keywords— GPSR; Greedy Forwarding; Perimeter Forwarding; VANET.
