Abstract

The invention relates to the field of mobile edge computing, in particular to an energy consumption optimization computing method and system based on mobile edge computing and an energy consumption optimization unloading method and system based on mobile edge. The computing method comprises the following steps: solving a series of cost solutions of time cost and energy consumption cost in each cost model by utilizing a biogeography optimization algorithm; separately sorting the series of cost solutions by adopting a fast non-dominated sorting algorithm, and separately obtaining a cost solutionset; calculating respective ideal solutions and negative ideal solutions according to a multi-criterion decision-making method TOPSIS, and finding out an optimal solution closest to the ideal solution from the cost solution set; substituting the optimal solution into a corresponding cost model, and determining the optimal time cost and energy consumption cost for unloading the current task by adopting edge equipment or central equipment and the optimal time cost and energy consumption cost for computing the current task by adopting local equipment. According to the method, the time, the energy consumption and the mobility of the mobile equipment can be comprehensively considered, and the effects of energy consumption computing and task unloading are ensured.

Description

technical field [0001] The present invention relates to the field of mobile edge computing, in particular to a method and system for energy optimization calculation and offloading based on mobile edge computing. Background technique [0002] In recent years, with the rapid development of 4G and 5G, computing functions have been decentralized. Edge devices (such as base stations, wireless access points, routers, laptops, etc.) have computing and communication capabilities, and will occupy an important role in the future. Location. Mobile Edge Computing (Mobile Edge Computing, MEC) integrates the computing and communication capabilities of the edge network, and allows the data generated by mobile applications to be processed directly on the above-mentioned edge devices instead of uploading to the central device server, so that massive edge devices will Complete distributed processing of data. The European Telecommunications Standards Institute (ETSI) established a working gr...
