Embodiment 1

[0045] Example 1: see Figure 1-Figure 4 This embodiment provides a regionalized hierarchical task migration method in mobile edge computing. According to the spatial and temporal distribution characteristics of user edge computing requirements, the migration of computing tasks is implemented to improve edge computing capacity utilization and user service quality. . The method is divided into three steps, namely, edge domain division, intra-domain task migration for load balancing, and inter-domain task migration based on terminal mobility awareness.

[0046] 1. Edge domain division

[0047] In this embodiment, the service area is divided, and edge servers with similar geographic locations are formed into an autonomous domain under unified management, which becomes an edge domain. After successfully determining the edge domain, select an edge server with the strongest computing capability as the edge agent, manage all edge servers in the edge domain, and obtain the load status of...

Abstract

The invention discloses a regional hierarchical task migration method in mobile edge computing, which comprises the following steps of: (1) performing domain management on a network edge formed by edge servers, dividing a plurality of edge servers with similar geographic positions into edge domains, and setting an edge agent in each edge domain so as to form an intra-domain level and an inter-domain level; (2), performing intra-domain task migration for load balancing; and (3) performing inter-domain task migration based on terminal mobility sensing: firstly, by the edge agents, sensing the position change of a terminal and determining whether a calculation task of the terminal needs to be migrated or not, and then completing task migration through a task migration negotiation mechanism between edge agents. The scheme solves the edge server load balancing problem and the mobile terminal position change problem so as to adapt to the dynamic change of the mobile edge computing environment.

Description

Technical field [0001] The invention relates to a regionalized hierarchical task migration method in mobile edge computing, and belongs to the technical field of task migration in edge computing. Background technique [0002] In recent years, the rapid development of mobile Internet and Internet of Things technology has spawned a large number of new applications in the fields of smart transportation, smart manufacturing, smart home, etc., making the user’s mobile terminal demand for data transmission, computing and processing soaring. Computing platforms and network infrastructure have brought a lot of pressure. At the same time, the cloud computing model is also difficult to meet the needs of users in terms of low latency and low communication costs. Therefore, mobile edge computing closer to users has become a focus of attention. [0003] In mobile edge computing, how to reasonably migrate computing tasks from terminals to edge servers / cloud platforms is the key to improving use...
