Techniques to Reduce Routing Overhead in AODV

In MANET, AODV is one of famous on-demand routing protocols. This paper identifies the inefficient elements during the route discovery process and local connectivity in AODV. Implemented technique is the combination of the Blocking expanding ring search and route packets as hello packets. The simulation results show that the new proposed scheme reduced the route load and has a better performance than AODV in terms of packet delivery ratio and Average end-to-end delay of data packets. The simulation is done through network Simulator-2 (ns2). Reduce end to end delay due to the reduction in network congestion and by improving route request latency, routing overhead and packet loss due to the higher success rate in the catching process which has positive impact on the network performance.
