Connectivity and Delay Aware Reliable Routing in Vehicular Ad hoc Networks.

In Vehicular Ad hoc Networks (VANETs) safety routing of information data packets is challenging issue, due to their delay-sensitive nature. The paper aims to resolve the issue of reliable and minimal delay routing in VANET. We propose a routing scheme to identify the reliable route with minimum delay from source to destination in VANETs. The routing scheme is in terms of probabilistic analysis of link duration between source and destination vehicles using border-node based most forward progress mechanism. Also the routing scheme selects best next hop vehicle out of the available neighboring vehicles belonging to source vehicle communication range border area. As the delay aware reliable routing is dynamic in nature handles the sparse and dense VANET scenarios to maximize the packet reception at the destination node. To examine the performance efficiency of the proposed work the performance parameters such as packet delivery ratio, latency and End-to-End delay are simulated and analyzed.
