Since vehicular network has characteristics such as node move fast

topology change rapidly

and AODV protocol broadcast-style routing has the problems such as short link survival time

long average end-to-end delay

a mode is proposed by calculating the link stability to improve AODV protocol. The new protocol choose shorter route and relatively stable routing efficiently by calculating angle forwarding considering two factors which are the longest projection and the longest link survival time when the node is broadcasting. In this way

the improved AODV protocol solves the problem of the network link fracture well

increases the packet delivery ratio and reduces average end-to-end delay. By using the NS2 network simulation software

the results show that the improved AODV protocol is superior to conventional model in packet delivery ratio

average end-to-end delay and throughput.
