A Sensor Data Query Method Based on Wavelet Synopsis
Accurately replying all queries of different users in Wireless Sensor Network is a challenging problem. The recent works solve this problem by approximate query based on sensor readings, For the need of precision, this model need to update frequently and the cost of communication increases very quickly. This paper proposes A sensor data query method based on wavelet synopsis, It constructs a wavelet synopsis in the process of data collecting, reduces the number of data, increases efficiency, reduces the communication cost.
