Abstract: Research the multi—QoS requirements of users.This paper puts forward a dynamic resource optimization algorithm based on multi—QoS requirements.Algorithm with chaos theory,combined with optimization algorithm and approximating the ideal solution sort thought.More dynamic resource form a linked list which is selected scheduling among QoS requirements of these resources,and parallel algorithms use iterative process to reduce the algorithm into a local optimum solution.The experiment results show that the improved algorithm is feasible and effective to solve the multi-QoS requirements problem,and has a certain practical value.
