UAV-based Intelligent Vehicular Network: Blockchain perspective

The increasing number of cars worldwide has resulted in significant problems such as fatalities, pollution, and traffic congestion. Developing a smart automotive system that promotes safe driving is a viable solution. However, the current vehicle system faces challenges such as data dependability, security, and ease of deployment. The current study proposes an intelligent vehicular system that is safe, deployable, and of high quality enabled by Unmanned Aerial Vehicle (UAVs). Specifically, the use of UAVs in the communication sector makes the networks vulnerable to cyber-attacks, which can cause significant damage to the industry. Henceforth, a blockchain-assisted registering and verifying mechanism is proposed for UAVs, smart vehicles, and roadside units. The presented research focuses on the blockchain-inspired security technique and the optimized positioning of UAVs to enhance the network's spectral efficacy. The study considers various communication-related criteria such as available bandwidth, the maximum number of connections a UAV can handle, and constraints when linking remote units to UAVs. The presented technique can be effectively incorporated into the existing vehicular network to provide secure and reliable communications. The performance of the presented technique is validated in experimental simulation in which enhanced results have been registered for statistical parameters.
