Optimization of Location Aware Routing Protocol for Wireless Adhoc Tactical Networks

Abstract—Mobile Adhoc Network (MANET) is a wireless technique which does not require any pre-existing infrastructure to function. It only requires wireless devices with sufficient battery to build the infrastructure dynamically. With the help of intermediate nodes, routes between source and destination are established by using any of the available Adhoc routing approaches. But due to high node mobility and frequent changes in routes, data transmission may break often, causing routes to recreate and update accordingly. Adhoc Routing Protocol we used in our thesis is Adhoc on Demand Distance Vector (AODV) which is a reactive protocol. AODV finds the route by broadcasting, which unnecessarily consumes bandwidth and processing at each node causing power constraints. Therefore, our thesis is focused on the optimization of AODV by using GPS to restrict packet broadcast and conserve power at nodes. Simulation environment used is Network Simulator 2. After simulation, results of Optimized AODV are then compared with traditional AODV and DSR for analysis purpose.
