Abstract: Vehicular Ad-Hoc network (VANET) is a highly dynamic decentralized wireless communication network and becoming promising transportation system due to rapid extension of safety and multimedia applications. However, both the applications demands fast and successful data dissemination to the destination nodes, design of reliable routing against intrinsic behavior of VANET is still challenging issue. Towards this, latest researches concentrated on mobility metric along with shortest path or minimum number of hops and showed improved performance in data transmission. Thus, in this paper, a new Mobility aware Cross layer Based Reliable Routing Protocol (CBRRP) is proposed for efficient data dissemination in the network. For optimal route selection, the proposed CBRRP applies several critical parameters, like link reliability factor, residual energy and neighbor node weight factor to Route Request (RREQ) packet and mobility metrics (relative velocity and distance) to Route Reply (RREP) control packet in the direction of destination vehicle. The performance of proposed CBRRP is compared with recent existing cross layer based routing protocol using Network Simulator (NS)-2. The simulation results clearly demonstrate that the proposed CBRRP offers lower energy consumption, end to end delay with improved link reliability for different urban traffic scenarios over existing approach.
