摘要:

边缘计算将网络边缘上的计算、存储等资源进行有机融合,构建成统一的用户服务平台,按就近服务原则对网络边缘节点任务请求及时响应并有效处理。由于边缘节点能力、资源、带宽、能源等受限,计算迁移是边缘计算的一个关键问题。综述了移动边缘计算的起因、演进和发展趋势,以从分布式计算、普适计算、云计算到边缘计算的演进历程为主线,对比分析了各阶段计算迁移的特点并对经典模型进行了评述;重点分析了边缘计算的最新研究进展及应用领域,研究并对比分析了基于能耗优化管理的移动边缘计算模型。最后提出了一个面向LTE应用和基于时分多址(time division multiple access,TDMA)的多用户边缘移动终端计算迁移策略系统。

Abstract:

Edge computing integrate the computing,storage and other resources on the edge of the network into a unified user service platform.According to the principle of nearest service,the network edge node task request is timely and correspondingly processed.Computational migration is a key issue in edge computing due to limited edge node capabilities,resources,bandwidth,and energy.The causes,evolution and development trends of mobile edge computing were reviewed from the distributed computing,pervasive computing,cloud computing to edge computing as the main line.The characteristics of computing migration at each stage were compared and analyzed,and the classical models were reviewed.The latest research progress and application fields of edge computing were focused on,mobile edge computing models based on energy optimization management were researched and compared.Finally,a time division multiple access based multi-user edge mobile terminal computing migration strategy system for LTE applications was proposed.

Key words: edge computing, computation offloading, IoT, cloud computing, mobile terminal
