摘要：This Due to high mobility of nodes in mobile ad hoc networks (MANETs), there exist frequent link breakages which lead to frequent path failures and route discoveries and energy level of nodes also frequently reduced. The overhead of a route discovery cannot be neglected. In a route discovery, broadcasting is a fundamental and effective data dissemination mechanism, where a mobile node blindly rebroadcasts the first received route request packets unless it has a route to the destination, and thus it causes the broadcast storm problem due to this more rebroadcast occurs causes more energy consumption. In this paper, we propose a neighbour coverage-based probabilistic rebroadcast protocol with implementation of good node detection algorithm for reducing routing overhead and energy consumption in MANETs. In order to effectively exploit the neighbour coverage knowledge, we propose a novel rebroadcast delay to determine the rebroadcast order, and then we can obtain the more accurate additional coverage ratio by sensing neighbour coverage knowledge. We also define a Good node detection Algorithm to provide the energy efficient network by selecting energy efficient nodes. By combining the Neighbour coverage probabilistic routing and good node detection algorithm, we gradually reduce rebroadcast and choosing energy efficient nodes during routing. Our approach combines the advantages of the neighbour coverage knowledge and Good node detection algorithm which can significantly decrease the number of retransmissions so as to reduce the routing overhead, and can also decrease the energy consumption
