Abstract: Vehicle Ad-hoc Networks (VANETs) permits vehicles to exchange running information among them. In this paper, we propose a system that can help a vehicle to judge the trustworthiness of a message. Based on the message's trustworthiness, messages are forwarded or discarded. In the proposed system the Intrusion Detection System (IDS) is used to monitor and collect information about the network traffic issues such as sudden brake, lane changing, slow down, etc. The IDS sends the messages to Road Side Unit (RSU). The RSU receives the messages from IDS and it will send the messages to the trust authority. The Trust Authority (TA) will check the messages for its trustworthiness. If the message is false, it will drop a false message. The proposed model compared with the Trust Scheme based on Vehicles Reports of Event model and simulation results shows that the proposed scheme shows better performance in all aspects than the existing model.
Keywords: VANETs, IDS, RSU, TA, and ITS.
