Reliable Multicast Routing Protocol For DTN Based Vehicular Ad Hoc Networks

Vehicular Ad Hoc Networks (VANET) are unique in their characteristics. Most of the VANET applications request one-to-many (group) communications. In this paper we discuss routing in DTN based VANET application. In our study we consider only the non-safety applications in the VANET environment. These applications request multicast routing. However the existing routing approaches which are mainly designed for safety application are not suitable. The basic routing paradigm store-carry-forward approach and DTN custodial responsibility will over overcome the limitations of the VANET application. Therefore we propose a Reliable Multicast Routing Protocol (RMRP) for non-safety applications that increases packet delivery ratio and reduces end-to-end delay. The simulation results are provided to verify the effectiveness of RMRP.
