Vehicular Ad-hoc Network (VANET) is a promising technology with a great potential for providing enhanced safety and convenience to vehicles. Majority of applications in VANET involve exchange of information amongst vehicles. Adversaries may take this as an advantage to disturb the network by disseminating false information. To address this problem, there is a need to assess the real trustworthiness of the reporting vehicles. Even in presence of on-board misbehavior detection system (MDS), the reliability of the same is subject to various limitations. In this paper, a MDS-based trust estimation model has been proposed to estimate the trustworthiness of event-reporting vehicles. An efficient algorithm has been proposed for estimating the trust value of event reporting node(s) based on MDS-based feedback of the peers. The simulation based experimental results are found to be encouraging and effective in real-time trust estimation with better accuracy.
