Mobile ad hoc networks (MANETs) consist of wireless mobile nodes that can dynamically and freely self-organize into arbitrary and temporary ad hoc network topologies. Due to high mobility of nodes, there exist frequent link breakages which lead to frequent path failures and route discoveries. In a route discovery, both cluster and broadcasting scheme is deployed, where a mobile node blindly rebroadcasts the first received route request packets unless it has a route to the destination, and it causes the broadcast storm problem. In cluster based multipath routing scheme is proposed for reducing routing overhead and energy consumption in MANETs. Multipath routing with cross layer framework is proposed to effectively exploit the load balancing and also to improve the network lifetime, accurate additional coverage ratio of cluster is determine the sensing cluster member coverage knowledge. Packet integrity is determined to provide the hop to hop authentication. By combining the cluster and cross layer frame work, a reasonable node lifetime is set to improve communication coverage. This scheme combines the advantages of the new enhanced RSA encryption/decryption scheme and energy consumption model which can significantly decrease the number of retransmissions so as to reduce the routing overhead, energy consumption, vulnerability of attackers and can also improve the network lifetime.
