Enhanced Local Repair AODV (ELRAODV)

AODV is one of the most common reactive protocols used in MANET. This paper proposes enhancement in popular on demand routing protocol AODV by improving its local repair mechanism. Enhanced local repair AODV (ELRAODV) makes mobile nodes more aware of the local connectivity by extending original HELLO to NHELLO message in AODV as proposed in. That extra information of the local neighbors allows ELRAODV to repair a route by sending a unicast request instead to broadcast in original AODV. The results show that ELRAODV performs better in terms of routing overhead, end to end delay than classic AODV. The simulation is done through network Simulator-2 (ns2).
