Developing Smart Control Platoon Algorithm for Secure VANET Environment

A vehicular ad hoc network (VANET) is a part of smart transportation. As a result of the vehicles being able to communicate with one another and share sensitive information, it is necessary to have an environment that can be trusted. Vehicles are clustered into platoons to ensure the secure transfer of information between them and select the platoon head of each platoon to control the vehicles. This paper proposes a smart control platoon system employing local and global trust schemes among vehicles in order to establish a secure environment. The platoon head calculates the local trust in each vehicle in the platoon. This allows the platoon head to authenticate trustworthy vehicles and prevent access to untrusted vehicles. In contrast, global trust is applied in the procedure of establishing the trust for the individual platoon.
