Using node accountability in credential based routing for mobile ad-hoc networks

This paper propose a secure and efficient routing scheme using a game theoretical approach and trust relationships between the nodes. We assume a ldquoBayesian Gamerdquo model among the nodes to find the optimal behavior of legitimate and malicious nodes. Moreover, using a ldquowatchdogrdquo mechanism and an ldquoacknowledgementrdquo mechanism (ACK), we construct trust relationships between the nodes.
