Abstract

In current routing protocols in ad hoc networks, a source node unnecessarily re-discovers the whole path when just one node moves, even if the rest of path needs not to be re-arranged. The time for re-discovery of the whole path may often take too long and affects the network efficiency adversely. In this paper, a local repair scheme has been proposed, where the source node recovers the route breakage caused by a shifting of node with an aid of adjacent node instead of re-routing the whole path. Adjacent nodes are under operation in adaptive promiscuous mode. Consequently, the proposed scheme has advantages in shortening the recovery time of the route breakage and in minimizing the energy consumption under promiscuous mode. The ns-2.27 simulator has been utilized for the evaluation of the proposed scheme.
