Futuristic blockchain based scalable and cost-effective 5G vehicular network architecture

In the present era, smart and efficient vehicular network architectures are necessary due to fast technological advancements in vehicles. Many problems arise in these complex networks, which can be handled using blockchain and the Internet of Things (IoT). We proposed a comprehensive blockchain based 5G vehicular network architecture, which is cost-effective, scalable, secure, and handles various vehicular network issues in a smart city. The proposed architecture consists of all essential components like reputation system, incentive mechanism, and priority based techniques to handle different limitations in the literature. Simulations results for different scenarios depict the high execution cost of a single controller node, minor node, and ordinary node as 106305, 85864, and 65491 gas values and transaction cost as 130521, 109824, and 89195 gas values. The results depict the effectiveness of the proposed architecture in terms of scalability, time and cost-effectiveness.
