基于 5G 的毫米波 (mmWave) 系统有望在智能交通系统 (ITS) 中实现 > 1Gbps 的通信。 ITS 依靠车对万物 (V2X) 通信在车辆之间共享信息。然而，通过 DSRC、3G、4G 和 LTE 等现有技术进行的 V2X 通信无法实现如此高的数据速率。虽然基于5G的毫米波可以支持超低延迟的V2X传输，但它存在波束对准困难以及由于车辆快速移动而导致的路由稳定性问题。动态车辆流量会导致频繁的光束错位，从而降低服务质量 (QoS) 性能。在本文中，我们首先提出了一种用于光束对准/选择目的的基于 3D 的位置检测方案。然后执行基于组的路由算法来选择安全路径以实现可信的数据传输。道路交通自动分段，将车辆分成不同的组，并选择每个组的组长并添加成员。组成员由组长通过椭圆曲线算法进行身份验证。执行霍夫曼编码来压缩数据并加密二进制文件。这种新颖的智能波束控制和安全稳定路由方案已在仿真中得到验证，表现出比现有方案更好的性能。
5G-based millimeter Waves (mmWave) systems have the prospective of enabling > 1Gbps communications in the Intelligent Transportation Systems (ITS). ITS relies on vehicle-to-everything (V2X) communications to share information among vehicles. However, the V2X Communications via existing technologies such as DSRC, 3G, 4G and LTE, are not able to achieve such a high data rate. Although 5G-based mmWave can support ultra-low-delay V2X transmissions, it comes with beam alignment difficulties as well as the routing stability issues due to rapid mobility of vehicles. The dynamic vehicle traffic causes frequent beam misalignment which tends to degrade the quality-of-service (QoS) performance. In this paper, we first propose a 3D-based position detection scheme for beam alignment/selection purpose. Then a group-based routing algorithm is performed to select a secure path for achieving trustworthy data transmissions. The road traffic is automatically segmented to divide the vehicles into different groups, and each group head is selected and members are added. Group members are authenticated by the group head via elliptic curve algorithms. Huffman coding is performed to compress the data and encrypt the binary files. This proposed novel intelligent beam control and secure stable routing scheme have been verified in simulations to demonstrate much better performance than existing schemes.
