随着车载物联网（IoT）应用的快速增长，迫切需要设计一种能够向道路上的车辆分发大量内容的方法。然而，由于在密集车辆环境中带宽有限，当前的蜂窝技术还不够。在本文中，我们提出了一种集成了许可的 Sub-6 GHz 频段、IEEE 802.11p 和毫米波通信的协议，用于车辆网络中的内容分发。所提出的协议采用基于集群的方法，其中采用基于模糊逻辑的算法来选择有效的网关节点，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，以实现高效的集群。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，所提出的协议在各种场景下都能取得显着的改进。
With the rapid increase of vehicular Internet of Things (IoT) applications, it is urgent to design an approach which is possible to distribute a large amount of contents to vehicles on the road. However, the current cellular technology is not sufficient due to its limited bandwidth in a dense vehicle environment. In this paper, we propose a protocol which integrates licensed Sub-6 GHz band, IEEE 802.11p, and mmWave communications for the content distribution 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 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 for achieving 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 improvement in various scenarios compared to the existing approaches.
