ε-approximate spatial-window aggregation algorithm in wireless sensor networks
An efficient ε-approximate spatial-window aggregate query processing technique was proposed to approximate aggregate values over arbitrary regions with arbitrary accuracy.A dynamic programming algorithm was devised to compute minimum number of data to refine approximate summation to reach arbitrary...
