基于极端价格过滤的云计算虚拟资源租赁算法
Virtual Resource Leasing Algorithm of Cloud Computing Based on Extreme Price Filtering
摘要
Abstract
In order to maximize the profit of service user virtual resource leasing in cloud computing,a new virtual resource leasing algorithm of cloud computing is proposed.By the cloud computing environment composed of three functional modules which are Virtual Resource Provider(VRP),Cloud Service Provider(CSP) and end user,it gives the virtual resource rental profit target.Considering the distribution of price and the urgency of tasks,for the weakly stationary price sequence,it uses the outlier detection method to filter the extreme price,designs the weak balance operator which uses the exponential function to control the integral shape of objective function's curve,and uses the non-uniform mutation operator to adjust local operators and effectively predict the future price.Then it gets the optimal leasing rental price of Virtual Machine(VM) processing tasks.Experimental results show that the proposed algorithm can improve the efficiency and rental cost of virual resource and reduce its usage cost.关键词
