Abstract

The invention relates to the technical field of big data computing, and discloses a computing unloading method and a computing unloading system in mobile edge computing, so as to realize that mobile equipment is really close to a cloud server providing computing service in physical meaning and reduce the access delay of an application. The method provided by the invention comprises the following steps of: obtaining the target product; calculating first required time and first required energy when the task runs locally; calculating second required time and second required energy for unloading operation of the task; and setting an unloading condition according to the first required time, the first required energy, the second required time and the second required energy, determining whether unloading calculation is needed or not according to the unloading condition, if yes, setting a server evaluation index, constructing a calculation model according to the server evaluation index, and determining an unloading target server according to the calculation model.

Description

technical field [0001] The present invention relates to the technical field of big data computing, in particular to a computing offloading method and system in mobile edge computing. Background technique [0002] With the rapid development of augmented reality and virtual reality in the field of mobile Internet services such as ultra-high-definition video, IoT applications such as crowd sensing and intelligent monitoring continue to emerge, and the requirements for the service level of mobile devices are getting higher and higher. These applications require rich Computing resources are accompanied by high energy consumption. However, mobile smart devices have limited computing power and battery life due to size limitations, and these applications cannot meet the user's satisfaction level. One of the main ways to solve this problem is to offload computationally intensive tasks to nearby servers with more abundant resources. This method is called computational offloading. ...
