Cloud Simulation Resource Scheduling Algorithm Based on Multi-dimension Quality of Service

Aiming at the shortcomings of cloud simulation task scheduling algorithm, this paper put forward cloud simulation scheduling algorithm based on multi-dimension QoS (Quality of Service). Firstly, analytic hierarchy process in economic field was introduced into the Resource scheduling algorithm to compute every dimensional parameters weight, then the tasks was allocated to appropriate resource according to customer satisfaction, QoS distance and loading equilibrium, etc. Finally, scheduling algorithm was analyzed by theory example and was simulated with CloudSim tool package. The experiment shows that this cloud simulation scheduling algorithm not only meets customer needs for multi-dimension QoS, but shortens the simulation finishing time and greatly improves simulation resource utility rate.
