Dynamic Statistical Algorithm of Spatial Data Access Laws

The tile access has dynamic features(server peer capability,storage device and hot tiles have dynamic features) and the Hotmap model based on the historical log information can not reflect the real system’s current global information.Reproduction and distribution will produce a huge network flow rate in a large scale distributed nodes environment.A dynamic statistics algorithm for the distribution rule of the spatial data based on P2P is proposed to resolve above-mentioned problems.The service capabilities of the service nodes are calculated in this algorithm.The node agents with good service capabilities are chosen preferentially in the group to fuse dynamic statistical information.The experimental results show that the algorithm can meet the need of dynamic statistics in large scale distributed modes environment with high efficiency.
