Fastest-Vehicle Multi-hop Routing in Vehicular Ad hoc Networks

Vehicle to vehicle communication has strong potential to be a mechanism to improve driver´s safety and is now emerging as a prominent research area all over the world. At present, vehicular networks are still not considered to be very efficient because of their rapid topology changes and their highly dynamic structure. However, there has been ongoing and progressive research and development in Vehicular Ad hoc Networks (VANETs) to support vehicle to vehicle communication, particularly in the area of routing in VANETs. In VANETs, routing schemes to reduced overhead and resource consumption is required to ensure successful message transfer within the network. The routing protocol proposed in this paper is based on a multi-hop transfer of a single message by discovering the most suitable vehicle within the transmission range instead of using single hop broadcast (flooding) scheme which results in high packet loss and collision rate. The simulation environment used for proposed algorithm is a tool which combines both network simulator and traffic simulator, known as NCTUns-6.0.
