There is an urgent need of effective trust management for vehicular ad-hoc networks (VANETs), given the dire consequences of acting on false information sent out by malicious peers in this context. In this paper, we first discuss the challenges for trust management caused by the important characteristics of VANET environments. We then survey existing trust models in multi-agent systems, mobile ad-hoc...
In this paper, we present a trust-based message propagation and evaluation framework in vehicular ad-hoc networks where peers share information regarding road condition or safety and others provide opinions about whether the information can be trusted. More specifically, our trust-based message propagation model collects and propagates peers' opinions in an efficient, secure and scalable way by dynamically...
In this paper we introduce a multi-faceted trust model of use for the application of ad-hoc vehicular networks (VANETs) - scenarios where agents representing drivers exchange information with other drivers regarding road and traffic conditions. We argue that there is a need to model trust in various dimensions and that combining these elements effectively can assist agents in making transportation...
