TIBCRPH: Traffic Infrastructure Based Cluster Routing Protocol with Handoff in VANET

Vehicular Ad Hoc network (VANET), is a hot topic that applying mobile Ad Hoc network (MANET) to ITS in recent years. Special environments and applications cause difficulties to the design of the routing protocols of VANET which can not use the exiting protocols well. Firstly, this paper introduces some concepts of VANET briefly, analyzes and compares some different kinds of existing routing protocols in VANET. Then, basing on the characteristics of the VANET, and utilizing the idea of cluster and handoff, a more efficient protocol is developed in this paper, which is dubbed Traffic Infrastructure Based Cluster Routing Protocol with Handoff (TIBCRPH). Finally, TIBCRPH is compared with other six typical routing protocols on node density and speed respectively by NS2. The results show that TIBCRPH performs better than some traditional routing protocols.
