摘要
为解决车辆高速移动性导致的车联网低时延高可靠性能下降问题,进行基于MEC(mobile edge computing,移动边缘计算)的车联网协作组网关键技术研究。首先,从车联网中MEC的独特性入手,进行低时延、高可靠车联网协作组网研究;然后,根据5G车联网中车辆编队与基于UAV(unmanned aerial vehicle,无人机)辅助的两个典型协作应用场景,进行基于MEC的协作资源管理关键技术研究;最后,探讨基于MEC的车联网资源管理关键技术的研究方向,为后续研究提供参考。
In order to solve the performance degration problem of low latency and high reliability caused by the high-speed mobility of vehicles,the key technologies of collaborative network based on MEC(mobile edge computing)were studied.Starting from the uniqueness of MEC in vehicular networks,the collaborative networking scheme with low latency and high reliability was introduced.According to the two most promising cooperative scenarios of vehicle platooning and UAV(unmanned aerial vehicle)assisted communication in 5G vehicular networks,the key technologies of cooperative resource management based on MEC were investigated.In addition,the research direction analysis of resource management based on MEC in vehicular networks provides a reference for further study.
