Embodiment

[0144] This embodiment simulates time-aware task migration in an "edge-cloud" collaborative environment.

[0145] To examine the average resource usage deviation of edge servers and the average transmission delay of computing tasks under each migration strategy, parameters need to be set. The relevant parameter value settings after multiple simulations are shown in Table 1.

[0146] Table 1

[0147] parameter value Number of virtual machines per edge server 10 Transmission rate / lpa between edge server and access point 1500Mbps Transfer rate between access points / l aa

1000Mbps

[0148] Such as figure 2 As shown, in the experiment, consider 3 workflow DAGs 1 ,DAG 2 ,DAG 3 . A total of 9 tasks, the tasks are divided into DAG 1 ={t 11 ,t 12 ,t 13}, DAG 2 ={t 21 ,t 22}, DAG 3 ={t 31 ,t 32 ,t 33 ,t 34}. In the case of 4 edge servers and 12 access points, CC={c 1 ,c 2 ,c 3 ,c 4}, AP={ap 1 ,ap 2 ,...,ap 12}. Wherein, ...

Abstract

The invention provides a mobile terminal task migration method based on time perception in a collaborative environment. The mobile terminal task migration method comprises the following steps: step 1,acquiring computing task information in an edge cloud collaborative environment and a deployment situation of an edge server; step 2, evaluating the average migration delay of the calculation task under each migration strategy; step 3, evaluating the energy consumption level of each edge server; and step 4, evaluating the utility value of each migration strategy through a standardization and normalization method, and selecting an optimal migration strategy. According to the method, a migration strategy is given in real time based on time perception according to edge cloud resource information, average migration delay of tasks is ensured, energy consumption of an edge server is optimized, calculation migration time can be shortened, and service performance can be improved.

Description

technical field [0001] The invention relates to the field of mobile network edge computing task planning, in particular to a time-aware mobile terminal task migration method in a collaborative environment. Background technique [0002] In recent years, the advancement of information technology and the maturity of a new generation of "edge-cloud" collaborative environment have led to the rapid development of mobile applications. However, the limited computing power and cache size of mobile devices hinder the speed of development to some extent. Moreover, more and more applications require lower latency, and time-aware task migration methods are becoming more and more important. Because these mobile applications rely on a large number of computing resources to meet the user's demand for service quality. In order to alleviate the resource constraints of mobile devices and improve the performance of generated mobile applications, mature cloud computing (Cloud Computing) is reg...
