Edge computing can effectively solve the problems of large transmission delay, insufficient user data security, high transmission bandwidth pressure, limited computing capabilities of terminal mobile devices, and high energy consumption in traditional cloud computing. Computing offloading is a key technology in edge computing. Concerning the research status and existing deficiencies of computing offloading technology, this study first introduces the architecture of edge computing and some applications and analyzes the four main influencing factors and corresponding specific conditions. Secondly, the algorithm strategy and the role of corresponding variables in the algorithm are analyzed in three decision objectives. Finally, it summarizes the current deficiencies in computing offloading.
