| 设计了自动驾驶车辆在高速移动场景下车联网的低时延数据传输方案.采用多径开环的数据传输方式，依靠功能强大的雾结点服务器，将宏结点与微结点组合接入点群，对用户的请求资源做出分配及调度.仿真实验表明，该方案数据传输的误码率略高于传统的长期演进（LTE）车联网方案的误码率，但时延可以降到1 ms以内. |

| Abstract: |
| In this paper,a low-latency data transmission scheme for autonomous vehicles in high-speed mobile scenarios was designed.In this proposed scheme the macro-nodes and micro-nodes were combined to form an access group dependent on a powerful fog node server so as to implement allocation and schedule of user-requested resources.The simulating experiment demonstrated that the delay of the present scheme was reduced to less than 1 ms compared to the traditional long term evolution (LTE) scheme while the data transmission error rate was slightly higher. |
