Towards Expanded Trust Management for Agents in Vehicular Ad-hoc Networks

摘要

In this paper, we examine the challenge of designing intelligent agents to enable the sharing of information between vehicles in mobile ad hoc vehicular networks (VANETs). Our focus is on developing a framework that models the trustworthiness of the agents of other vehicles, in order to receive the most effective reports. We develop a multi-faceted trust modeling framework that incorporates role-based trust, experience-based trust and majority-based trust and that is able to restrict the number of reports that are received. We include an algorithm that proposes how to integrate these various dimensions of trust, along with experimentation to validate the benefit of our approach, emphasizing the importance of each of the different facets that are included. In addition, we clarify how our approach is able to meet various critical challenges for trust modeling in VANETs. The result is an important methodology to enable vehicle to vehicle communication via intelligent agents.
