VANET Event Verification Based on User Trust

Abstract

The main objective of this paper is to present a real-time system to improve road safety through the use of event alerts. A collaborative community where users can share traffic warnings to help other users is here proposed. The method is based both on the verification votes of the users, and on their profiles and trust levels. Each user is assigned a trust level depending on its previous behavior. The proposal is based on the assumption that the system will be run in every driver mobile device. Thus, smartphones are the connectors between users and the community, using the cloud, and between the system and the users, using audio notifications.
