面向未来移动通信的移动边缘计算研究综述OA北大核心CSTPCD

Mobile edge computing(MEC)has become one of the key technologies for future-oriented communica-tions by offloading the computing and storage tasks of mobile terminals from centralized data centers to edge grids to satisfy the diverse device service demands in complex communication scenarios.The basic concept and basic frame-work of MEC technology were introduced by describing the development history from cloud computing,fog compu-ting to mobile edge computing.On this basis,the research progress of MEC was discussed in four aspects,namely,computation offloading,resource allocation,cache management,and security protection.A detailed overview of the relevant research results was provided.Then,studies on several typical application scenarios of edge computing such as IoT,MEC combined with blockchain,AI-assisted MEC systems,integrated sensing and communication,and cloud-edge collaboration were summarized.It demonstrated the potential benefits of MEC in 6G in terms of con-stituting an intelligent,efficient and secure communication network.Finally,the challenges faced by MEC research in convergence innovation from the aspects of interoperability,security risk,mobility management and scalability were pointed out,as well as the advantages and development trends in the directions of ultra-reliable low-latency communications,communication-sensing-computing integration and satellite-ground fusion mobile communication.The development trend of it in the future mobile communication was also summarized and outlooked.
