Abstract:

In order to effectively improve the utilization efficiency of computing resources and reduce the cost of running tasks, we propose a dynamically coordinated allocation mechanism of cloud computing resources based on benefit game. We utilize time matrix and cost matrix as mission effectiveness measure, design a benefit game model, and employ its effectiveness calculation equation to calculate the equation of the model. Thus the best resource allocation policy is obtained. Our mechanism can guarantee a reasonable allocation of  computing resources on demand to meet all the resource  requirements for normal task performance, and simultaneously maximize the benefits of task performance. Simulations and experimental results comparison  show that the proposed mechanism achieves better results in aspects such as task completion time, average cost of task execution and the success rate of task completion.
