Vehicle to Vehicle (V2V) networking is a promising technology that ensures secure and efficient transportation by allowing vehicles to communicate and share messages to alert each other. In such a network, reputation can be used to establish trust between vehicles in disconnected areas. While a vehicle with a low reputation could be less trustworthy, a vehicle with a high reputation is supposed to be more reliable. This concept can be implemented if every vehicle is given a reputation score. Reputation score can be determined by a reputation server linked to a Security Credential Management System, which uses data from onboard sensors or past interactions with other vehicles. In this work, we incorporate a reputation system to maximize the chance of making an accurate decision based on the received message. By adopting the pre-signature scheme, vehicles dynamically assess and rely on the most trustworthy information available, even in the most challenging and infrastructure-limited environment. The simulation shows the effectiveness achieved by our proposed schema using reputation values to improve the safety and efficiency of offline V2V communication by preventing accidents and attacks and reducing traffic congestion.
