Research on multi-objective dynamic cloud service strategy
Most of the existing cloud service strategies are scheduling algorithm based on users satisfaction or QoS.The former does not consider physical resource utilization, while the latter ignores the satisfaction of the users experience.This paper proposes a multi-objective cloud service model, which is based on the users dynamic demand and resource utilization.In addition, it designs a multi-objective optimization algorithm based on improved PSO algorithm (ADW-PSO) to solve the model.To evaluate the performance of proposed algorithm, we extend cloudsim package to simulate the cloud environment, and compare with the traditional PSO algorithm and the double adaptive GA algorithm.The simulation results show that the ADW-PSO algorithm outperforms other two algorithms on users experience and resource utilization, which can improve the quality of cloud services obviously.
