Abstract: The staggering growth of the number of vehicles worldwide has become acritical challenge resulting in tragic incidents, environment pollution,congestion, etc. Therefore, one of the promising approaches is to design asmart vehicular system as it is beneficial to drive safely. Present vehicularsystem lacks data reliability, security, and easy deployment. Motivated bythese issues, this paper addresses a drone-enabled intelligent vehicularsystem, which is secure, easy to deploy and reliable in quality. Nevertheless,an increase in the number of operating drones in the communication networksmakes them more vulnerable towards the cyber-attacks, which can completelysabotage the communication infrastructure. To tackle these problems, we proposea blockchain-based registration and authentication system for the entities suchas drones, smart vehicles (SVs) and roadside units (RSUs). This paper is mainlyfocused on the blockchain-based secure system design and the optimal placementof drones to improve the spectral efficiency of the overall network. Inparticular, we investigate the association of RSUs with the drones byconsidering multiple communication-related factors such as available bandwidth,maximum number of links a drone can support, and backhaul limitations. We showthat the proposed model can easily be overlaid on the current vehicular networkreaping benefits of secure and reliable communications.
