TRUNCMAN: Trust based routing mechanism using non-cooperative movement in mobile ad-hoc network

The Routing Protocol available in present generation of MANET focuses mainly on the performance and only a little capability against the malicious attacks. The foremost concerned security issue in MANET is to protect the network layer from malicious attacks, thereby identifying and preventing malicious nodes. The selection of optimal path for routing and the detection of security attacks cannot be achieved with the traditional approaches. Even though there are many secure routing protocol available for the optimal route discovery and defense against different types of attacks, they focuses mainly on specific objects and where not able to defend against the particular attacks. Since the MANET environment is highly dynamic in nature, managing trust in such a kind of environment is highly crucial as well as maintaining cooperation for building a safe and secure route is imperative. The proposed protocol ensures the trust among the nodes in the network and isolates the malicious node from the network by invoking a noncooperative movement.
