Reducing Routing Overhead In Manet Using Ncpr Protocol

Ms.Manjula.R, Mr.Santhosh.R

Mobile Ad hoc network is a collection of wireless mobile nodes. MANET is able to form a temporary network without any centralized administration. Due to high mobility of nodes in Mobile Ad hoc Network. There exist frequent link breakages and path failures. In a route discovery mobile nodes blindly retransmits the route request packets to the neighbor nodes unless it finds the route to its destination, and thus it causes the broadcast storm problem. in order to effectively exploit the neighbor coverage knowledge, we propose a rebroadcast delay to determine rebroadcast order, we also define a connectivity factor to keep network connectivity factor we set a rebroadcast probability. Hence it combines the advantages of neighbor coverage knowledge and probabilistic mechanism, it significantly decrease the number of retransmissions to reduce the routing overhead and also to improve the routing performance.
