Problems solved by technology

[0003] Computational offloading and resource allocation methods in mobile edge computing are crucial, and some researches have been done, but most of them are aimed at the case of single base station user offloading, and the user only offloads one task at a time, partly considering the multi-base station user’s For example, NING Zhaolong, DONG Peiran, KONG Xiangjie, et al. ACooperative Partial Computation Offloading Scheme for Mobile Edge Computing Enabled Internet of Things[J]. IEEE Internet of Things Journal1, 2019, 6(3): 4804-4814. However, it does not solve the problem of base station access selection for users with overlapping coverage of multiple base stations and the problem of offloading of multi-user and multi-task

Embodiment Construction

[0029] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] The application scene of the method of the present invention is as attached figure 2 As shown, it consists of a remote cloud node and multiple base stations configured with MEC servers, and multiple user terminals are distributed within the coverage of each base station. Among them, there are one-to-many mapping relationships between remote cloud nodes and base stations, and between base stations and mobile terminal devices. Terminal devices access base stations through wireless networks, and base stations can offload tasks to remote cloud nodes through the Internet and accept remote cloud nodes. The calculation result of the node response is returned to the terminal device.

[0031] Because some users are covered by multiple base stations, during task processing, users can only select one base station to access. For example attached...

Abstract

The invention discloses a method for offloading computing tasks of a mobile user. The steps include: on the premise that the method meets the computing resource constraints of an edge computing server, perform offload scheduling for each task request and select a suitable base station for the user to ensure that the user terminal completes the task. The system delay and terminal energy consumption of the task are minimized, and the user's base station selection, offloading decision and task scheduling scheme are obtained. The present invention greatly reduces computational complexity, improves user satisfaction, and realizes the goal of optimizing system time delay and terminal energy consumption.

Description

technical field [0001] The invention relates to task unloading in a wireless communication system, in particular to a method for unloading computing tasks of mobile users. Background technique [0002] In recent years, with the development of technologies such as the Internet of Things, artificial intelligence, and virtual reality, high-energy-consuming computing-intensive services have continued to grow. The conflict between computing-intensive applications and resource-constrained mobile computing systems has brought great challenges to the development of future mobile services. brought unprecedented challenges. In order to meet this challenge, the mobile cloud computing technology MCC is usually adopted, which offloads the computing tasks on the mobile terminal to the resource-rich remote cloud for completion. However, the traditional MCC method has the disadvantages of long delay and low reliability caused by the data transmission through the wide area network. In rece...
