In mobile ad hoc networks (MANETs), there is frequently disconnected a route consisting of multi-
hop from a source to a destination because of the dynamic nature such as the topology change
caused by nodes’ mobility. To overcome this situation, existing routing protocols for MANETs have
performed route repair scheme to repair the disconnected route. However, existing reactive routing
protocols have the problem which is that a source node unnecessarily performs re-discovers the
whole path when just one node moves, even if the rest of path needs not to be re-arranged.
Therefore, the time for re-discovery of the whole path may often take too long. To solve the problem,
we propose a new local repair scheme using promiscuous mode. Our scheme is mainly
composed of two parts: adaptive promiscuous mode and quick local repair scheme. Adaptive
promiscuous mode is to repeat the switching processes between promiscuous mode and
nonpromiscuous mode to overcome energy limit caused by using promiscuous mode in overall
time and quick local repair scheme is to fast perform the local re-route discovery process with the
information of the active connection in the local area acquired by promiscuous mode. With
simulation in the various number of connection, We demonstrate the better network performances
achieved with the proposed schemes as compared with AODV as reference model that do not
provide local repair scheme.
