Complex task query based on cloud computing Resource: Improved approximate skyline algorithm

Cloud computing aims at sharing all resource completely, which include CPU´s computing ability, store capacity, network bandwidth and etc. Most cloud computing users task requisitions are among multiple target requisition which are hard to be met by these requisition conditions simultaneously. So it is the key to find out the most approximate node machine among large number of node machines in cloud computing model. This paper presents an improved approximate skyline algorithm to hunt to most approximate node machine economically, and provides an alternative reference for the coming task allocation.
