A computing offload distribution method for edge servers

Abstract

The invention discloses a computing offloading distribution method of an edge server. The method includes the following steps: constructing a vector to be optimized according to the proportion of tasks performed by each user terminal on the edge server to each user terminal task, using the first target function, the second objective sub-function and the third objective sub-function to construct the objective optimization function, the first objective sub-function is the sum of the calculation time of local execution tasks on all user terminals and the calculation time of execution tasks on the edge server, the second The objective sub-function is the sum of the energy consumption of tasks performed locally on all user terminals and the energy consumption of tasks performed on the edge server. The third objective sub-function is the sum of the charges generated by tasks performed on the edge server. The objective optimization function is used to solve the problem of The optimal value of the optimization vector is configured according to the optimal value of the vector to be optimized, and the proportion of the tasks performed by each user terminal on the edge server to the tasks of each user terminal is correspondingly configured.

Description

technical field [0001] The invention belongs to the field of cloud edge server computing, and in particular relates to a computing offloading distribution method for edge servers. Background technique [0002] With the rapid development of the Internet and the popularization of 4G / 5G wireless networks, the era of the Internet of Everything has come, and the rapid increase in the number of network edge devices has caused the explosive growth of data generated by such devices, which has reached the ZB level. In the era of centralized big data processing centered on the cloud computing model, its key technologies have been unable to efficiently process the data generated by network edge devices, mainly in the following aspects: 1) The centralized cloud computing capacity increases linearly and cannot match the explosive growth 2) The network edge devices need to transmit massive data to the cloud center, and the cloud center returns the processed results to the user, resulting ...
