A novel architecture and multi-hop protocol to support intervehicular communication is proposed. The protocol uses ‘latency’ as a metric to find routes. We introduce the concept of a Routing Server (RS), which tries and keeps up-to-date information about the state of the network, i.e. the network topology, and the latency associated at each node averaged over a short time. Route discovery is now carried out by sending a Route Request packet directly to the RS, rather than flooding the network. We call this model ‘Server Supported Routing (SSR)’. A simulation study is carried and the performance of SSR compared with Dynamic Source Routing (DSR) protocol. It is found that SSR performs better than DSR over longer hops, faster rate of topology change, and high offered load in the network. The study also reveals that DSR is much more sensitive to changes in the network than SSR.
