论文摘要
随着智能车辆的开发，车辆之间的安全性和可靠性通信已成为在车辆互联网（IOV）中解决的关键问题。区块链由于其权力下放，不可遗憾和集体维护的优势而被认为是可行的解决方案。但是，IOV中节点的计算能力有限，而区块链的共识机制要求系统中的矿工具有强大的计算能力来进行挖掘计算。因此，它无法满足要求，这是在IOV中应用区块链的挑战。实际上，可以通过使用边缘计算来实现区块链在IOV中的应用。边缘计算的关键实体是边缘服务器（ESS）。路边节点（RSU）可以作为IOV中的边缘计算的ESS部署。我们研究了ES部署方案，用于覆盖IOV中更多的车辆节点，并提出了一种随机算法来计算近似解决方案。最后，我们模拟了拟议方案的性能，并将其与其他部署方案进行了比较。
With the development of intelligent vehicles, security and reliability communication between vehicles has become a key problem to be solved in Internet of vehicles(IoVs). Blockchain is considered as a feasible solution due to its advantages of decentralization, unforgeability and collective maintenance. However, the computing power of nodes in IoVs is limited, while the consensus mechanism of blockchain requires that the miners in the system have strong computing power for mining calculation. It consequently cannot satisfy the requirements, which is the challenges for the application of blockchain in IoVs. In fact, the application of blockchain in IoVs can be implemented by employing edge computing. The key entity of edge computing is the edge servers(ESs). Roadside nodes(RSUs) can be deployed as ESs of edge computing in IoVs. We have studied the ES deployment scheme for covering more vehicle nodes in IoVs, and propose a randomized algorithm to calculate approximation solutions. Finally, we simulated the performance of the proposed scheme and compared it with other deployment schemes.
