The present invention relates to the field of mobile edge computing, and is an energy consumption optimization calculation and offloading method and system based on mobile edge computing; the calculation method includes solving the time cost and energy consumption cost in each cost model by using a biogeographical optimization algorithm A series of cost solutions; use the fast non-dominated sorting algorithm to sort the series of cost solutions separately, and obtain the cost solution sets respectively; according to the multi-criteria decision-making method TOPSIS, calculate the respective ideal solutions and negative ideal solutions, and find out from the cost solution sets The optimal solution that is closest to the ideal solution; the optimal solution is substituted into the corresponding cost model to determine the optimal time cost and energy cost for the current task to be offloaded by the edge device or the central device, and the current task uses the local The optimal time cost and energy consumption cost for the calculation of the device, the present invention can comprehensively consider the time, energy consumption and mobility of the mobile device, and ensure the effect of energy consumption calculation and task offloading.
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...
