Route stability and energy aware based AODV in MANET

Most present routing protocols for MANET, as the optimal route follow the shortest route for routing between source to destination with minimum hop count. However the delay between two communicating nodes, signal strength of received packet, total remaining energy and draining rate of nodes are never considered through this shortest route. It makes difficult to select a long lasting route between the nodes in network. To achieve route stability, we given a new protocol, Route Stability and Energy Aware based RSEA-AODV, which selects the route according to above four performance metrics and it minimize the chance of route breakage because of two factor i.e. distance between two communicating node and energy depletion. In proposed work during route discovery we consider signal strength, delay, total remaining energy, and draining rate of nodes to decide whether to add that node in path or not. All these parameters are compared with defined threshold value, if calculated value satisfy the threshold condition then it process the route request packet otherwise it drops the packet. Simulation (NS-2) results have been shown to state that RSEA-AODV has better performance comparing with AODV routing protocol in terms of network lifetime, normalized routing overhead, packet delivery ratio, throughput and total number of dead nodes during simulation.
