随着车载物联网应用的快速增加，迫切需要设计一种移动的边缘计算架构，使道路上的车辆能够分发和处理大量内容。从通信的角度来看，由于密集车辆环境中的有限带宽，当前蜂窝技术面临挑战。在本文中，我们提出了一个多访问边缘计算框架和相应的通信协议，它集成了许可的Sub-6 GHz频段，IEEE 802.11p和毫米波（mmWave）通信，用于车载网络中的内容分发和处理。所提出的协议使用基于簇的方法，其中采用基于模糊逻辑的算法来选择有效的网关节点，该网关节点桥接许可的Sub-6 GHz通信和毫米波通信，以最大化整体网络吞吐量。IEEE 802.11p车对车通信用于在车辆之间共享信息，以实现有效的聚类。我们进行了广泛的模拟，以评估所提出的协议在各种网络条件下的性能。仿真结果表明，与现有方法相比，该协议在各种场景下均能取得显著的性能改善。
With the rapid increase of vehicular Internet of things applications, it is urgent to design a mobile edge computing architecture, which is possible to distribute and process a large amount of contents with vehicles on the road. From a communication perspective, the current cellular technology faces challenges due to the limited bandwidth in a dense vehicle environment. In this paper, we propose a multi-access edge computing framework and the corresponding communication protocol which integrates licensed Sub-6 GHz band, IEEE 802.11p, and millimeter wave (mmWave) communications for the content distribution and processing in vehicular networks. The proposed protocol uses a cluster-based approach, where a fuzzy logic-based algorithm is employed to select efficient gateway nodes which bridge the licensed Sub-6 GHz communication and the mmWave communication in order to maximize the overall network throughput. IEEE 802.11p vehicle-to-vehicle communication is used to share information among vehicles in order to achieve efficient clustering. We conduct extensive simulations to evaluate the performance of the proposed protocol under various network conditions. Simulation results show that the proposed protocol can achieve significant improvements in various scenarios compared with the existing approaches.
