Modified Approach for Secure Routing and Power Awareness in Mobile Ad Hoc Network

Mobile Ad Hoc Networks (MANETs) show better and valuable performance in the circumstances where the generally used wireless networks fail to work. In order to make routing in MANETs secure, number of security based routing protocols have been proposed in the literature but none of them is compliant with the MANETs requirement of security and low power consumption. The monitoring operation is distributed among a few set of nodes called monitor nodes. The set of monitor nodes is selected sporadically which makes the proposed method adaptable to the two important concerns of MANETs: dynamic network topology and energy constraint devices. The proposed method detects malicious packet dropping and packet modification attacks. This algorithm has also been developed to reduce the packet dropping attack in MANET which has been simulated on MATLAB and demonstrated an increase in packet delivery ratio, throughput while decrease in average end to end packet delay.
