Embodiment Construction

[0058] Such as figure 1 As shown, the mobile unloading migration algorithm based on improved HRRN algorithm and multi-attribute decision-making of the present invention comprises the following steps:

[0059] Step 1: A single wireless body area network generates multiple tasks with different priorities at a certain moment, if they can be processed locally, they are directly processed locally, otherwise they are uploaded to the edge server;

[0060] During specific implementation, a single wireless body area network generates multiple tasks with different priorities at a certain moment according to the wireless body area network priority specification of IEEE802.15.6.

[0061] Step 2: Establish the benefit function of the edge server, define the benefit function as the weighting of delay and energy consumption, calculate the benefit value of all edge servers, and use the edge server with high benefit value as the initial edge server of the current task;

[0062] The step 2 is ...

Abstract

The invention relates to a mobile unloading migration algorithm based on an improved HRRN (High Resolution Response Next) algorithm and a multi-attribute decision. The method comprises the following steps: step 1, a single wireless body area network generates a plurality of tasks with different priorities at a certain moment, if the tasks can be locally processed, the tasks are directly locally processed, otherwise, the tasks are uploaded to an edge server; 2, establishing a benefit function of an edge server, and taking the edge server with a high benefit value as an initial edge server of the current task; 3, judging whether the current edge server is suitable or not; 4, judging whether the edge server meets two criteria or not, wherein one of the criteria can be used as a candidate edgeserver; and step 5, according to the benefit function of the edge server established in the step 2, calculating the benefit values of all candidate edge servers, and selecting the edge server with the highest benefit value to migrate.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a mobile unloading migration algorithm based on improved HRRN algorithm and multi-attribute decision-making. Background technique [0002] With the development of mobile communication technology and the popularization of smart terminals, various network services and applications continue to emerge, and users have higher and higher requirements for network performance such as network service quality and request delay. Although the processing power of the central processing unit of the smart terminal is getting stronger and stronger, it is still not enough to process huge applications in a short period of time. In addition, the battery power consumption and self-loss of smart terminals are also a major problem. To solve this problem, the industry has proposed mobile edge computing and edge offloading technologies. [0003] Mobile edge computing (MEC) refers to unfami...
