移动边缘计算卸载技术综述

Survey on Mobile Edge Computing Offloading Technology

移动边缘计算(Mobile Edge Computing,MEC)将云服务器的计算资源扩展到更靠近用户一侧的网络边缘,使得用户可以将任务卸载到边缘服务器,从而克服原先云计算中将任务卸载到云服务器所带来的高时延问题。首先介绍了移动边缘计算的基本概念、基本框架和应用场景,然后围绕卸载决策、联合资源分配的卸载决策分别从单MEC服务器和多MEC服务器两种场景总结了任务卸载技术的研究现状,最后结合当前MEC卸载技术中存在的不足展望了未来MEC卸载技术的研究。

Mobile edge computing(MEC)expands the computing resources of cloud servers to the edge of the network closer to the user side,allowing users to offload tasks to edge servers,thus overcoming the problem of high latency for offloading tasks to cloud servers in the cloud computing.Firstly,this paper introduces the basic concepts,basic framework and application scenarios of mobile edge computing.Then,it summarizes the research status of task offloading technology from two scenarios of single MEC server and multiple MEC servers,with focuse on offloading decisions,joint resource allocation and offloading decisions.Finally,for the shortcomings in the current MEC offloading technology,it gives prospect of the future research on MEC offloading technology.
