The mobility of nodes in mobile ad-hoc network leads to frequent link breakages and path failures which in turn lead to route discoveries. For route discovery, broadcasting is an efficient routing mechanism. Broadcasting induces excessive redundant retransmissions of RREQ packets and thus causes routing overhead. The overhead of route discovery cannot be neglected. Limiting the number of rebroadcasts can optimize the broadcasting. An enhanced probabilistic rebroadcast based on neighbor coverage area is used here to reduce the number of retransmissions and thus the routing overhead.
