EFFICIENT PACKET DELIVERY FRAMEWORK USING GEO-CAST ROUTING APPROACH FOR A VEHICULAR AD-HOC NETWORK (VANET)

In recent years, the technology of Vehicular Ad-hoc Networks(VANET's) communication has become more popular, allowing people to share road information with each other and use it while driving.Vehicular Ad-hoc Networks are special type of Mobile Ad-hoc Networks (MANET's) in which nodes are highly motile, so the network topology changes very fast. In order to form the communication there are several routing protocols provide to optimal path for delivery of packets. In this paper, the Geo-cast routing(GPRs) are applied for both urban and highway areas based on traffic environment. The two protocols Coverage Aware Geo-cast Routing(CAGR) in urban vehicular networks and Information Propagation Speed Analysis(IPSA)in highway vehicular networks are discussed.The path formation from source vehicle to destination vehicle based on different criteria are considered. The results are analyzed using MATLAB
