Optimal path finding algorithm using neighbor position in a Wireless Ad Hoc Network

A Wireless Ad Hoc Network (WANET) is a self configuring network where nodes, connected by wireless links and can move freely by changing its topology constantly. Wireless ad hoc network routing protocols are mainly based on reactive routing that uses minimum hop count. A WANET uses hop count as a parameter to measure the performance of the wireless link between nodes. The wireless links over a long distance may be slow or lossy that leads to poor throughput. Due to mobility, the links between distant node is broken quickly might be accused congestion. Therefore, among the multiple paths from source node to destination node we need to select a path which is more stable and avoids the congestion even if links broken. In this paper we proposed an algorithm OMRAODV that finds an optimal stable path among the paths available in between source to destination node. Simulation results show that OMRAODV has better performance than MAODV in terms of the metrics: End-to-End Delay, Packets Delivery Ratio, Throughput, Power Consumption, Network Load, Packet Received and Packet Lost.
