An improved cross layer cooperative routing for vehicular networks

Cooperative routing has gained promising approach in Adhoc networks where nodes are assumed to be static. Recently there has been an increased heed in the cellular and vehicular Adhoc Networks (VANETs) where links between vehicles to vehicle are not fixed and inefficient. Towards this there exists onlyc one cooperative routing scheme, Cross layer Cooperative Routing (CLCR) for route discovery on the fly similar to AODV, which requires more transmission power and energy consumption due to redundant transmission of Hello messages. Here an efficient cross layer routing mechanism is identified by the use of weighted Neighbor stability algorithm (WNS), which provides more stable, reliable routing path. Furthermore based on the simulation results using Network Simulator 2(NS-2) shows the new routing mechanism shows graceful performance in terms of packet delivery ratio, average end to end delay and throughput.
