Power efficient and light weight approach for secure multicast tree construction in MANETs

Routing is prime importance in mobile ad-hoc networks as it is complex and the environment is extremely dynamic. On the other hand multicast routing supports one to many communication and it is efficient with channel usage, bandwidth. Routing algorithms define how data travels in a multicast network. In this paper we take a close look at attacks in multicast networks and propose a secure lightweight failure resilient solution for MAODV. Our protocol is divided into two phases where first phase elect a most energy remaining node as a vice leader. Second, the mechanism can encourage the malicious nodes honestly by providing punishment and incentives. Simulation result shows that the proposed scheme did not exhaust the nodes and a high level of detection rate against without introducing and significant traffic.
