Energy Saving Strategy based on Adaptive Transmission Power Scheme and Adaptive Network Configuration for WSN

For full deployment and exploitation of Wireless Sensor Network energy consumption remains as a major obstacle nowadays. Energy awareness and energy efficiency are two desirable characteristics of Wireless Sensor Network. To minimize the energy consumption from both the sensor node level and network level an energy efficient strategy is proposed. By using localization algorithm the physical location of the sensors after they have been deployed is determined. After that the distance between transmitter and receiver is estimated before available transmission to minimize the communication energy consumption. Then the lowest power needed to transmit the measurement data is determined and calculated.
