1. Introduction
The rapid development of the Fifth Generation (5G) and the Internet of Things (10 T) has resulted in a significant increase in the number of user devices connected to the Internet. This has been accompanied by a considerable rise in the volume of data and a proliferation of sophisticated mobile applications and services. Among these applications, those that are computationally intensive, such as pattern recognition, interactive games, and virtual/augmented reality, not only consume a considerable amount of computing resources and energy, but also require ultra-low response latency [1]. However, the limitations of hardware technology result in the computing, storage and energy resources of mobile devices being constrained to varying degrees. As a result, it is difficult to provide effective support for the deployment of latency-sensitive and computationally intensive applications.
