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.

在当今时代，由于车辆技术的快速进步，需要智能高效的车辆网络架构。这些复杂的网络中出现了许多问题，可以使用区块链和物联网 (IoT) 来处理。我们提出了一个全面的基于区块链的 5G 车载网络架构，该架构具有成本效益、可扩展性、安全性，并且可以处理智慧城市中的各种车载网络问题。提议的架构由所有基本组件组成，如声誉系统、激励机制和基于优先级的技术，以处理文献中的不同限制。不同场景的模拟结果显示，单个控制器节点、次要节点和普通节点的高执行成本为 106305、85864 和 65491 gas 值，交易成本为 130521、109824、和 89195 个气体值。结果描述了所提出架构在可扩展性、时间和成本效益方面的有效性。
