Road safety and security are the most challenging topics in recent times. Vehicular ad hoc network, an active part of the intelligent transportation system, provides the advanced technology to tackle the various security and safety issues of vehicles. Vehicle is an integral part of the VANET that often gets compromised with numerous types of attackers and starts to perform malicious activities. To provide secure and smooth communication among the vehicles, we are required to detect those infected nodes and remove them from the network. In this paper, we proposed a trust-based security algorithm based on cooperation among the vehicles. The proposed algorithm detects the malicious activities, mainly centered on packet dropping, with the help of the trust-based security measurements. Our proposed model primarily based on the two things one is cooperation among the vehicles, and the other is monitoring network traffic of moving vehicles. Simulation analysis and results demonstrate the incredible growth in the performance of the AODV routing under the proposed algorithm. We present the simulation of the proposed algorithm in network simulator NS-2, and result evaluation by using network parameters like successful data delivery fraction and end-to-end delay. Simulation and result analysis show that our algorithm works better to detect malicious entities (vehicles) in the network and enhances the performance of the network of moving vehicles.
