A Blockchain enabled location-privacy preserving scheme for vehicular ad-hoc networks

n the imminent future, with the immense need for improving road safety and demand for enhancing the overall driving experience, the utility of vehicular ad-hoc networks technology (VANET) becomes well pronounced. But, the major setbacks of VANET are centralized architecture and the lack of privacy-preserving mechanisms. As it is evident, blockchain technology is gaining attention because of the features like decentralization, distributive, cooperative maintenance and non-tampering nature. This paper presents a decentralized architecture of VANET comprising blockchain technology. The proposed blockchain-based model for VANET works in four stages: blockchain network initialization, vehicle registration, pseudonym upload, and blockchain maintenance. This can efficiently solve the problems emerging in centralized architectures and helps in resolving trust issues between the entities. We propose an algorithm for protecting location privacy and providing anonymity. Experimental analysis proves that the given architecture performs better than the existing solutions.
