In mobile ad hoc networks the nodes are in mobile nature for that reason frequent link breakages will occur, which causes frequent route discoveries and path failures. In route discovery broadcasting is the most important concept, initially in a network all the nodes receive the route request packets apart from the destination, route, as a result it starts the broadcast storm problem. In this paper, the authors explored a protocol based on probabilistic rebroadcast mechanism that is predicated on neighbor coverage, decreasing routing located in MANETs (Mobile Ad hoc NETworks).
