A Futuristic Blockchain based Vehicular Network Architecture and Trust Management System

In a complex network of smart vehicles, some issues arise related to security, privacy, selfishness of nodes and node failures. We have proposed an architecture of vehicular network in a smart city based on blockchain. Some scenarios and design principles are also provided. Contrary to prior architectures of vehicular networks, our proposed model provides robustness, scalability, adaptability, trust management as well as privacy and security. It eliminates the issue of selfish nodes and malicious nodes. Unlike other vehicular architectures, it also takes into account the passengers' medical facilities and fault tolerance. In case of any failure of sensors or nodes, system will effectively tackle it. Both big data storage and fast computation are not possible on vehicles end. This can be handled by moving these processes to static nodes and data center. Malicious behaviour of nodes is handled using trust values and incentives mechanism in order to motivate nodes to work effectively while assigning penalty for selfish nodes.
