Directional Location Verification and Routing in Vehicular Ad-Hoc Network

Abstract

Vehicular ad-hoc network (VANET) is an autonomous system of mobile vehicles in which vehicles are a source of information. In VANET, direct communication between vehicles provides high-level safety and hassle-free drive. Large moving vehicles such as trucks or buses may affect direct communication of vehicles as a nonline of sight (NLOS) may occur. NLOS restricts direct communication of vehicles. Even the corresponding vehicle is within the communication range of the communicating vehicle. To overcome the NLOS problem and verify the location of the vehicles, this chapter has presented a routing mechanism, namely Directional Location Verification and Routing (DLVR) in Vehicular Ad-hoc Network. DLVR model prevents the false location information of the nodes by reduced packet drop and increased packet delivery ratio. Before transmitting data packets DLVR verifies data packets through reliability check. Through simulation work, it has shown the proposed DLVR model reduced packet drop and increased packet delivery ratio which increases the network performance.
