Guaranteed QoS resource scheduling scheme based on improved shuffled frog leaping algorithm in cloud environment

The resource scheduling scheme for cloud computing environment,that provides QoS(Quality of Service)guarantees,is presented in this paper based on improved Shuffled Frog Leaping Algorithm(SFLA).Two encoding structures for SFLA are introduced in accordance with the characters of tasks and resources,the QoS of scheduling scheme is defined,and the improved SFLA based on the QoS selections is given in ditails.The experimental results in CloudSim platform show that the algorithms are efficient.
