Problems solved by technology

[0004] Existing research on network scenarios based on multi-task offloading users seldom considers the optimization problem of users with the maximum task processing delay. However, for delay-sensitive users, this will make it difficult to guarantee transmission performance and user experience. Therefore, there is an urgent need for a An optimization scheme based on the user's maximum task processing delay

Abstract

The invention relates to a multitask unloading method based on edge server cooperation, and belongs to the field of wireless communication. The method comprises the following steps: S1, modeling an edge server variable; S2, modeling user task characteristics; S3, modeling a user task segmentation variable, and unloading the variable and a time slot distribution variable; S4, modeling user task local execution delay; S5, modeling the task execution delay of the edge server; s6, modeling user task scheduling limiting conditions; and S7, determining a user task unloading strategy based on the minimization of the maximum task processing delay of the user. The optimal user task scheduling strategy and the optimal unloading ratio under the condition that the task is effectively executed can be ensured, and the user delay minimization is realized.

Description

technical field [0001] The invention belongs to the field of wireless communication, and relates to a multi-task offloading method for edge server cooperation. Background technique [0002] With the development of the mobile Internet and the popularization of smart terminals, new applications such as augmented reality (AR), virtual reality and natural language processing are constantly emerging. However, the computing resource-intensive characteristics of various new applications pose severe challenges to the task processing capabilities of intelligent terminals. To solve the above problems, Mobile Edge Computing (MEC) technology emerges as the times require. This technology deploys the MEC server with strong computing power to the Radio Access Network (RAN), and supports users to offload tasks to the MEC server for computing, which can effectively reduce the terminal task execution delay and energy consumption. Significantly improve user quality of service (Quality of Ser...
