Abstract

In Mobile Ad Hoc Networks (MANET), the traditional way of communication performed by the nodes by choosing the geographical location causes complexity. Also the existence of malicious nodes in the transmission path may drop the data packet or influence the routing messages. In order to overcome these issues, in this study, we propose a secure multipath routing for improving data confidentiality in MANET. Initially multiple paths are established between source and destination for data transmission. In the established paths, the monitoring nodes are chosen based on the parameters such as available bandwidth and residual energy using swarm intelligence. These monitoring nodes involve in malicious node detection and informing the source of the attack. When the source wants to transmit the data to the destination, it eliminates the path with malicious nodes and bypasses the data through other alternate path. Then a secure key management technique is deployed to defend against the malicious attack. By simulation results, we show that the proposed approach enhances the data confidentiality as well as minimizes the overhead.
