Trust Based Secure Routing Mechanism in Mobile Adhoc Networks for Enhancing the Routing Performances

Abstract

Mobile Adhoc Networks enforces certain level of challenges for the researchers since they operate without a fixed infrastructure. Moreover the constant movement of nodes gives additional challenges while implementing any type of solutions. Similarly enforcing secure mode of routing in mobile adhoc networks creates lot of hurdles for the implementers. This paper addresses these issues, by computing the trust of each node and updating the trust tables of the respective nodes and the cluster head. This paper focus in designing a trusted secure mechanism for routing. The objective of this work is to calculate the trust of nodes using various trust methods. Later the calculated trust is updated with the trust table of the cluster head by forming a web of trust. This will enable a secure channel of communication among the adhoc nodes. After incorporating the newly computed trust, the routing performance of well known routing protocol say AODV, is evaluated for various routing parameters and it is compared with the performance of Trusted AODV(TODV).
