Reputation Management in Vehicular Ad Hoc Networks

Vehicular ad hoc networks (VANETs) have become a promising application of mobile ad-hoc networks (MANETs). Since an inaccurate traffic warning message will impact drivers' decisions, and misguide drivers' behavior, one of the main challenges in VANETs is to forward messages in such a way that the information content can be trusted by receiving nodes. In this paper, we proposed a reputation management system to prevent the spread of bogus messages. An event-based protocol is designed to collect and aggregate reputation information. We also present a fuzzy computational model to represent reputations. The simulation results show that our proposed system can effectively filter false messages in VANET environments.
