Abstract

We propose an effective Local Repair scheme for AODV in mobile ad-hoc network environment. Even though the existing Local Repair scheme for AODV routing protocol can recover the disconnected path in some ways, however, they can not utilize the pre-connected routing nodes when we handle the nodes in Ad-hoc environment. In order to utilize the pre-connected routing nodes in recovering the path more effectively, we use a designated candidate nodes and changed Hello messages. The candidate nodes are used to recover the disconnected path using the pre-connected routing information. The Hello messages provides multipath for candidate nodes. This scheme produces better results with less control packets with faster path recovery time.
