摘要
In this paper, According to the topology characteristics of VANET, We proposed a new routing protocol that is suitable for VANET communications within the cluster based on AODV: AODV with predicting node trend (AODV-PNT). There are two major improvements in AODV-PNT: (1) Routing metric improvements and calculate Total Weight of the Route (TWR). (2) Predict node's future TWR and calculate stable threshold W in a bid to choose a suitable relay node. Finally, we simulated AODV-PNT using ns2. The simulation results show that AODV-PNT is able to achieve better routing performances in packet deliver ratio, average end-to-end delay and routing overheads as compared to AODV.
