Abstract :
The high mobility of nodes in mobile ad hoc networks (MANETs), causes frequent link breakages which lead to frequent path failures and route discoveries. The overhead of a route discovery cannot be neglected. Broadcasting is based on effective data dissemination mechanism, where a mobile node blindly rebroadcasts the route request packets unless it has a route to the destination, which causes the broadcast storm problem. For this problem a neighbor coverage-based probabilistic rebroadcast protocol for reducing routing overhead is used. In order to effectively exploit the neighbor coverage knowledge and a novel rebroadcast delay to determine the rebroadcast order, for obtaining the more accurate additional coverage ratio by sensing neighbor coverage knowledge. Admission Control mechanism is combined together with NCPR to improve the routing performance, which can find the effective route discovery and route maintenance. It provides multiple routes back up recovery and improves centralized coordination among network routes. The proposed protocol significantly decreases the number of retransmissions, increases data rate speed delivery based on network traffic.  And it is effectively maximize the network throughput   in the mobile ad-hoc network.
