A NOVEL APPROACH FOR MINIMIZING CONGESTION AND ENHANCING NETWORK LIFETIME IN MANETs

Most existing routing protocols follow the shortest route for routing between sources to destination with minimum hop count. However the delay between two communicating nodes, energy consumption of nodes and network lifetime are never considered through this shortest route. It makes difficult to select a long lasting route between the nodes in network. To achieve optimal path, we have proposed a new Modified AODV (M_AODV), which selects the route according to above three performance metrics and it minimize the chance of congestion. Simulation results shows that M_AODV has better performance comparing with AODV routing protocol in terms of network lifetime, packet delivery ratio, throughput, Packet loss and Routing Delay during simulation.
