Mobile cloud calculation adaptive virtual machine scheduling method based on improved particle swarm

Abstract

The invention discloses a mobile cloud calculation adaptive virtual machine scheduling method based on an improved particle swarm. The method comprises the following steps of considering four resources of a CPU, a memory, a network bandwidth and a hard disk, regarding a virtual machine scheduling model as a boxing problem, constructing three objective functions of minimum energy consumption, maximum utility and minimum server number, and establishing a multi-objective optimized virtual machine scheduling model VMSA-PSOEU in combination with constraint conditions; according to the virtual machine scheduling method, a boxing problem is converted into a constrained multi-objective optimization problem, a collected virtual machine request serves as input, a VMSA-PSOEU model is combined, the multi-objective optimization problem is solved through an improved particle swarm algorithm, an optimal solution is obtained, and the optimal solution is a final virtual machine scheduling scheme. Aiming at the problem of high energy consumption of the cloud center, how to effectively reduce the energy consumption of the data center is fully considered from the four resource dimensions, Meanwhile, the cloud center efficiently schedules and manages the virtual resources, so that the effectiveness of the cloud center is improved, and the energy consumption of the cloud data center is effectively reduced.

Problems solved by technology

[0005] Although the existing virtual machine scheduling methods of mobile cloud centers reduce the energy consumption of cloud centers to a certain extent, there are still some deficiencies. On the one hand, the existing virtual machine scheduling methods of mobile cloud computing cannot meet the current needs. , if it cannot meet the large-scale virtual machine scheduling requirements; on the other hand, most of the existing virtual machine scheduling strategies are not considered comprehensively, or only considered from a different perspective, such as only considering CPU energy consumption instead of Does not consider the energy consumption of other components
