Effective Usage of Rebroadcast Delay to Minimize Routing Overhead in MANET

Broadcasting is effective data dissemination mechanism for route discovery in Mobile Ad-hoc Network (MANET). Although it has many benefits, it also causes some problems such as the broadcast storm problem, which is pertaining to redundant retransmission, collision, and contention. Many techniques have been proposed to solve them but none of them guarantees the lowest bound. To overcome broadcast storm problem and reduce routing overhead, proposed system minimizes routing overhead using rebroadcast delay and rebroadcast probability. It also considers Nodes having highest energy will broadcast the RREQ packets to its neighbors. This system is implemented over the MANET network and simulated using Network Simulator (NS2). This project contributes that neighbor nodes of the failed link take the backup in case of link failure so as to decrease the number of retransmissions and minimizes routing overhead, also helps in improving the routing performance.
