N2 - An Ad-hoc NETwork consists of several mobile nodes that communicate with each other with no infrastructure. In the Vehicle Ad-hoc NETwork(VANET), moving vehicles are organized into a mobile wireless Ad-hoc NETwork to share online traffic information. VANET is a mobile Ad-hoc NETwork (MANET). However, routing protocols designed for MANET cannot be directly applied to VANET because of the intrinsic characteristics of VANET. One of the most important routing protocols used in Ad-hoc NETwork is AODV (Ad hoc On-Demand Distance Vector Routing). In this paper, we improved AODV based on velocity and direction classification (VDRP). By comparing the velocity and direction of other nodes with those of the local node, VDRP classifies the mobility relationship among the nodes into the following four categories: standing, following, unstable, and worst. Mobility relationship determines the suitable routing strategy that could improve the stability of routing. At the end of the study, we conducted a simulation test. Compared with AODV protocol, data transmitted successfully are 15 more in TCP connection, and time delay is reduced 50 in CBR connection when the account of the nodes is large. Simulation results show that VDRP performs better than AODV protocol in urban road circumstance.
