Embodiment Construction

[0067] In order to enable those skilled in the art to better understand the technical problems, technical solutions, and technical effects in this application, the method for joint wireless resource management and task offloading optimization in an ultra-dense network of the present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods Detailed description.

[0068] The application scenario adopted in the embodiment of the present invention is multi-user task offloading in an ultra-dense network, specifically as figure 1 shown. The architecture includes a macro base station and M microcell base stations. Both the macro base station and the small base station deploy MEC servers with computing power, which can serve the tasks offloaded by UEs. The difference lies in the difference in computing power. The set of base stations is S= ={1,2,...,S}. We set the set of UEs as N=={1,2,...,N}, and each UE has a task ...

Abstract

The invention provides a joint radio resource management and task unloading optimization method for solving the problem of user unloading benefit (energy consumption and time delay quantitative weighted sum) taking a user as a center in an ultra-dense network. To maximize user offload benefits, optimization management of both channel selection and user upload power wireless resources is alternately updated in an iterative optimization process. According to the method, the defects of calculation performance and battery capacity of a user can be overcome, the execution time delay of the user canbe effectively saved through task unloading, the energy consumption is reduced, and the user experience quality is better improved.

Description

technical field [0001] The invention belongs to the two fields of 5G communication and edge computing, and in particular relates to a joint wireless resource management and task offloading optimization method in an ultra-dense network. Background technique [0002] According to the Cisco white paper, the monthly global mobile data traffic in 2022 will be nearly seven times that of 2017 (up to 77EB / month), and mobile devices account for the highest proportion of mobile data traffic (about 90%). It can be seen that the use of user equipment (User Equipment, UE) is a major contributor to wireless communication traffic. In today's rapidly developing society, mobile devices are becoming more and more intelligent and multimedia, and many new services and applications have emerged, such as augmented reality, wearable smart devices, and Internet of Vehicles. However, such business and application tasks cannot be completed only by resources such as the computing power and battery ca...
