车辆物联网（IoT）包括用于大量重要应用的使能技术，包括协作自动驾驶和先进的交通系统。由于车辆的移动性、严格的应用要求和有限的通信资源，传统的集中式控制无法为联网车辆提供足够的服务质量，因此需要在附近采用分散式方法来满足延迟敏感和关键任务应用的要求。分散式系统也更能抵抗单点故障问题和恶意攻击。区块链技术由于其实现分散、透明和防篡改系统的能力而引起了人们的极大兴趣。有许多研究集中在使用区块链管理车辆环境中的数据和交易。然而，区块链在车载环境中的应用也面临着一些技术挑战。在本文中，我们首先解释了区块链和车辆物联网的基本原理。然后，我们通过讨论研究问题和技术问题，对车辆物联网区块链的现有研究工作进行了文献综述。在此之后，我们指出了一些未来的研究问题，考虑到区块链和车载物联网的特点。
The vehicular Internet of Things (IoT) comprises enabling technologies for a large number of important applications including collaborative autonomous driving and advanced transportation systems. Due to the mobility of vehicles, strict application requirements, and limited communication resources, the conventional centralized control fails to provide sufficient quality of service for connected vehicles, so a decentralized approach is required in the vicinity to satisfy the requirements of delay-sensitive and mission-critical applications. A decentralized system is also more resistant to the single point of failure problem and malicious attacks. Blockchain technology has been attracting great interest due to its capability of achieving a decentralized, transparent, and tamper-resistant system. There are many studies focusing on the use of blockchain in managing data and transactions in vehicular environments. However, the application of blockchain in vehicular environments also faces some technical challenges. In this paper, we first explain the fundamentals of blockchain and vehicular IoT. Then, we conduct a literature review on the existing research efforts of the blockchain for vehicular IoT by discussing the research problems and technical issues. After that, we point out some future research issues considering the characteristics of both blockchain and vehicular IoT.
