Embodiment Construction

[0035] The present invention is further described below in conjunction with accompanying drawing.

[0036] To realize the pre-scheduling of data resources in the edge computing environment, it is necessary to build a preliminary edge computing experimental environment. Such as figure 1 , 2 As shown, the experimental environment of edge computing needs to be able to perform task preprocessing, data preprocessing, deploy corresponding scheduling strategies, and ensure data consistency, including the following steps:

[0037] 1) Task preprocessing: the edge server obtains the relevant tasks generated by the terminal, and models the relevant tasks. The task set is set to in Assuming that the instruction length of the compiled task is known, len i means t i instruction length; Indicates scheduling t i the edge node; means t i the required dataset;

[0038] Preprocess the task set generated by the terminal, through the intelligent router or base station, have a certain...

Abstract

The invention discloses a data resource pre-scheduling method based on an edge computing environment. According to the method, in an edge computing environment, preprocessing the obtained data throughan intelligent router or a base station; the edge server schedules and integrates the preprocessed data; relaxation adjustment is carried out on data based on a task generated by a terminal, a data node support degree and a task node dependency degree are calculated in combination with a data correlation degree, data placement and task scheduling are simplified by utilizing the data node supportdegree and the task node dependency degree, and the consistency of data among multiple edge nodes is maintained through a Raft algorithm. Meanwhile, related tasks obtained from a cloud center depend on historical data of data request frequency, a cuckoo algorithm is used for continuously optimizing a scheduling model, and pre-scheduling of data resources in an edge computing environment is achieved.

Description

technical field [0001] The invention belongs to the technical field of information services, and in particular relates to a method for pre-scheduling data resources based on edge computing. Background technique [0002] With the popularization of the Internet and the development of mobile terminals, various embedded devices, wireless sensors, and smart terminals have become increasingly powerful, and a large number of smart devices with sensing, computing, and storage capabilities have already met the conditions for forming an intelligent system network. Most of the traditional processing methods aggregate their data interaction to the cloud for processing. However, with the continuous increase of data volume and the diversified requirements of data processing, cloud-based big data processing faces many challenges. [0003] Take the current hot self-driving car as an example. From the perspective of product form, the self-driving car is more like a "mobile data center". Bec...
