Establishing trust and security in ad-hoc networks has been a long studied problem. Several methods have been proposed for evaluation and dissemination of trust in such networks, with the goal of providing secure data paths. We propose a mechanism to utilize trust metrics derived from various methods for secure routing. Our scheme can be used in with exiting on-demand routing protocols with minimal modification. We highlight scenarios that establish the need for associating trust with a link, rather than just a node. Our scheme incorporates both link and node trust to avoid adversarial paths in a distributed manner. We validate via simulation, the security properties of our scheme in an ad-hoc network.
