Embodiment

[0112] This embodiment simulates the dynamic scheduling of computing tasks in a wireless metropolitan area network.

[0113] Such as figure 2 As shown, in the experiment, we consider the situation of 6 computing tasks, 3 clouds, and 9 access points, that is, CL={cl 1 ,cl 2 ,cl 3}, AP={ap 1 ,ap 2 ,...,ap 9},T={t 1 ,t 2 ,...,t 6}. Among them, the number of virtual machines in each cloud is 10. The information of each computing task is shown in Table 1.

[0114] Table 1 Computing task information

[0115]

[0116] It can be seen from Table 1 that t 1 and t 2 There is a data conflict between t 3 and t 5 There is a data conflict between t 4 and t 5 Execution required more resources than cl 2 Therefore, in order to ensure the smooth execution of tasks and protect the privacy of users, the initial task scheduling strategy needs to be modified.

[0117] if t 2 still in cl 1 on the implementation, then t 1 Needs to be rescheduled, can migrate to cl 2 or cl 3...

Abstract

The invention discloses a computing migration method taking into account privacy protection in a wireless metropolitan area network environment. The method includes: 1. Obtaining cloud resource requirements and supply conditions and equipment deployment information in a wireless metropolitan area network; 2. Obtaining the information of computing tasks Conflict status and privacy leakage status; 3. According to the characteristics of computing tasks, formulate a dynamic scheduling method for computing tasks; 4. According to the scheduling strategy, calculate the average resource usage deviation of Dooyun and the transmission delay of computing tasks; 5. For various The objective function value under the scheduling strategy is evaluated, and the optimal strategy for managing the cloud computing task of the wireless metropolitan area network enhanced service function is selected. According to the resource information, the present invention provides a scheduling strategy in real time, which not only protects user privacy, but also optimizes cloud load balance, thereby reducing computing migration time and improving service performance.

Description

technical field [0001] The invention relates to the fields of privacy protection and mobile network edge computing task planning, in particular to a computing migration method that takes into account privacy protection in a wireless metropolitan area network environment. Background technique [0002] In recent years, with the development of mobile technology and the popularization of wireless networks, mobile applications have developed rapidly. In mobile applications, especially in an IoT (Internet of Things, Internet of Things) environment, mobile terminals need to perform a large number of data calculations to meet users' requirements for service quality. However, mobile terminals have problems such as insufficient storage space, limited computing resources, poor computing power, sensitive delay or large data calculation volume, etc., and it is difficult to achieve the desired effect of users, thereby reducing the service performance of mobile computing (Mobile Computing)...
