Problems solved by technology

[0005] In order to solve the problem that the existing computing offloading research of mobile edge computing does not take into account the different characteristics of different types of tasks, so that the tasks can obtain the best delay characteristics that meet the characteristics of their tasks, the present invention proposes a mobile edge computing based on task classification. Edge computing task scheduling method, based on task classification, reduces task processing delay and increases the number of tasks processed by the mobile terminal

Embodiment Construction

[0043] In order to facilitate those skilled in the art to understand the technical content of the present invention, the content of the present invention will be further explained below in conjunction with the accompanying drawings.

[0044] Such as figure 1 Shown is a model diagram of mobile terminals and mobile edge servers based on cellular wireless communication systems, including base stations, mobile terminals (mobile phones, tablet computers, etc.), and mobile edge servers.

[0045] Base station: The mobile terminal wireless network establishes a connection with the base station, and the base station establishes a connection with the server through a wired network. However, after the data is sent from the mobile terminal to the base station, it is assumed to arrive at the server (ignoring the delay between the base station and the server).

[0046] Mobile terminal: The mobile terminal can only interact directly with the base station through the wireless network, althoug...

Abstract

The invention discloses a mobile edge computing task scheduling method based on task classification. The invention aims to solve the problem that the task cannot obtain the optimal delay characteristic meeting the task characteristics of the task due to the fact that different characteristics of different types of tasks are not considered in the calculation unloading research of the existing mobile edge calculation. The method comprises the steps that firstly, task types are determined, initial task amount parameters of the task types are given, and optimal task amount parameters correspondingto the task types are calculated through an NTPO algorithm; based on the optimal task parameter of each task type, each task is uploaded by adopting a BOPTUD algorithm; the time delay of task processing can be obviously reduced, and the number of tasks capable of being processed by the mobile terminal is increased under the same energy consumption of the mobile terminal.

Description

technical field [0001] The invention belongs to the field of mobile edge computing, in particular to a task scheduling technology based on mobile edge computing. Background technique [0002] With the maturity of 4G technology, more and more mobile terminal users are getting used to watching online video through diversified mobile terminals. This new trend poses a huge challenge to both wireless network operators and online video providers. Video services consume a lot of wireless resources and bandwidth, and network video providers hope to provide differentiated services for their VIP users under fierce competition, but the current network cannot provide differentiated services based on wireless base stations. With the coming of the 5G era, the above demands will become more prominent. [0003] The proposal of mobile edge computing technology can well meet the above business needs. Mobile Edge Computing (Mobile Edge Computing) is to deploy some servers on the edge close t...
