Anonymous Misbehavior Detection in Mobile Ad Hoc Networks

In this paper, we propose the first protocol that can achieve anonymous misbehavior detection in mobile ad hoc networks. On the one hand, our protocol can provide anonymity for the witness who reports observed misbehavior. Together with a distributed trust mechanism, our protocol can identify malicious or selfish users in an anonymous manner. On the other hand, the misuse of witness anonymity is prevented in such a way that any malicious user who broadcasts multiple claims against the same user for the same reason can be identified. An exemplary scenario is simulated to show the necessities of witness anonymity in mobile ad hoc networks and the effectiveness of our protocol in achieving such anonymity.
