摘要
移动边缘计算(mobile edge computing,MEC)通过将计算任务卸载至边缘服务器,降低网络负荷,减少传输时延,提升用户服务体验。因此,MEC受到了广泛关注,并成为5G的关键技术。资源分配作为MEC的主要问题,在提升能量效率、缩短任务时延和节约成本方面具有非常重大的研究意义。首先,介绍了MEC的基本概念、参考架构和技术优势;然后,从技术层面和经济层面归纳总结了MEC中最新的资源分配和定价策略;最后,讨论了MEC资源分配和定价策略中可能存在的问题与挑战,并提出了一些可行的解决方案,为后续研究发展提供参考。
Mobile edge computing(MEC)has ability of reducing network load and transmission delay,and improv-ing user service experience by offloading computing tasks to edge servers.Therefore,MEC has attracted extensive attention and become a key technology of 5G.As one of the main issues of MEC,resource allocation has great significance in improving energy efficiency,shortening task delay and reducing cost.Firstly,the basic concept,reference architecture and technical advantages of MEC were introduced.Then,the up-to-date achievements of resources allocation and pricing strategies were summarized from both technical and economic aspects.Finally,some possible problems and challenges associated with resource allocation and pricing strategies in MEC were discussed,and the enabling methods to address these challenges were also proposed to provide reference for subsequent research and development.
