Abstract: This paper analyzes data transmission characteristics of the radio Wireless Sensor Network(WSN). Based on this, the best energy transmitting power which can make the largest network life is gained, and a policy is put forward to prolong network life and keep a high rate of data collection. Theoretical analysis result shows that the strategy ensures end-to-end under the premise of the reliability of the network and extends the life of WSN, which can play the important instructing role for WSN.
