An Improved AODV Routing Protocol for VANETs
The rise in the number of vehicles has led to a rapid increasing need for vehicle communication today. The emerging Vehicular Ad Hoc Network (VANET) is becoming more and more important, which can provide intelligent transportation application, comfort application and other services for people in vehicles. In order to provide stable routes and obtain good performance in VANET, proper routing protocols must be designed. At present, some kinds of routing protocol have been used in VANET. As one of the most important routing protocols used in Mobile Ad Hoc Networks (MANET), AODV routing protocol is also used in VANET, and is often evaluated with other kinds of protocols. However, due to the different characteristics of the two networks, AODV protocol suffers poor performances when it is applied in VANET directly. So in our improved AODV routing protocol in VANET, we make two steps optimization in route discovery and route selection process to improve the route stability and decrease overhead. Simulation results show that our proposed AODV protocol can get better performances in forms of link stability and packet delivery ratio.
