移动边缘计算中基于中继辅助计算方法综述 postprint

Abstract: In order to meet the challenging requirements of next generation networks in terms of capacity, deployment cost and coverage, Mobile Edge Computing (MEC) is usually necessary to complete the latency-sensitive and computation-intensive task with the assistance of relay nodes. This paper first introduces the basic architecture of relay-assisted MEC system, and then summarizes the up-to-date research methods of relay- assisted MEC system from three aspects: task offloading, resource allocation and relay selection. Furthermore, the possible problems and challenges of the existing methods are discussed and analyzed, and some feasible solutions are put forward to provide reference for follow-up research and development.
