移动边缘计算技术现状与几个关键问题的研究综述

A survey on the mobile edge computing paradigm and its related research progresses

任务计算卸载技术是为了解决本地计算资源不足而产生的,长期以来主要在云端、移动端等场景中出现.随着边缘计算时代的到来,移动边缘计算端(MEC)的任务卸载技术也受到广泛的关注和研究.文章从三个方面进行了论述:①介绍了MEC的网络架构及其部署方案,并对不同的部署方案做了分析和对比;②从移动计算卸载决策、资源分配和卸载系统这几个角度进行研究;③总结归纳了目前MEC的任务计算卸载技术所面临的移动性管理、安全管理以及服务管理等方面的挑战.

The task computing offloading technology is generated to solve the problem of limited local computing resources. It has mainly appearing in the cloud and mobile scenes for a long time. With the advent of edge computing, are the task offloading technology of the mobile edge computing end (MEC) has also received extensive attention and research. This paper first introduces the network architecture and deployment scheme of MEC, and analyzes and compares different deployment scenarios. Then it studies from the perspectives of mobile computing offload decision, resource allocation and offloading system. Finally, it summarizes challenges faced by the current MEC s mission calulation in mobility management, security management, and service management.
