To improve the energy efficiency is one key problem of Wireless Sensor Networks (WSN) research. Analyzed the spatial and temporal characteristics of the space- time signal of the monitored area, a sensor node deployment method based on the spatial bandwidth of the signal, an information de- redundance algorithm based on the spatial and temporal bandwidth of the signal and related routing policy are provided. This algorithm eliminates efficiently the spatial and temporal redundance of the information sending to data sink, and save the energy of the network.
