Embodiment Construction

[0067] The energy consumption and safety-aware oriented service workflow scheduling method provided by the present invention will be further described below with reference to the accompanying drawings. figure 1 The overall framework of service workflow fault-tolerant scheduling in MEC environment is shown. figure 2 Shown is the process flow of this method, and the specific steps are as follows:

[0068] Step (1): Establish a model; establish a result quality model for energy consumption issues, and then establish a security model to provide security services for task scheduling and provide security service overhead methods. The steps are as follows:

[0069] Step (1.1): establish a quality of result (QoR) model; the present invention uses the adjustable QoR level to adjust the task workload, when the most ideal precision that an application can achieve is A*, if the actual precision is A, then The model of QoR class q is as follows:

[0070] q=1-(A * -A) / A * =A / A * ∈[0,1...

Abstract

The invention discloses a service workflow scheduling method oriented to energy consumption and safety perception, which is characterized in that safety service overhead is calculated by using the workload of safety service, the safety service is quantified, and meanwhile, a QoR model is established, so that a user can adjust a QoR level q according to the quality of a required result, and the energy consumption and the time are jointly considered. The result quality is adjusted by using the adjustable QoR level, and when the QoR level is lower, the workload required by processing the same data by using an original processing method is smaller, and the processing time required by the task is shorter, so that the energy consumption of mobile equipment is reduced. And meanwhile, the NSGA-II algorithm is utilized to carry out comprehensive optimization, so that the work flow delay and the equipment energy consumption are reduced.

Description

technical field [0001] The invention belongs to the field of service workflow scheduling, and in particular relates to a service workflow scheduling method oriented to energy consumption and security perception. Background technique [0002] With the continuous development of 5G communication and Internet of Things technology, a large number of emerging mobile applications continue to emerge, and the limited computing resources of mobile devices can no longer meet user needs. The emergence of Mobile Edge Computing (MEC) mode provides corresponding resource requirements for mobile devices and assists mobile users in processing computing-intensive applications. Specifically, mobile users can offload part or all of the tasks to the edge server for execution, so as to reduce the energy consumption of mobile devices and the delay of mobile applications. [0003] However, with the continuous development of applications, the demand for computing resources required by the service w...
