This paper describes that improving the life time of sensor by optimizing the energy utilized by the sensor. It is very difficult to replace the battery and also it is very expensive.The energy efficient communication is achieved by choosing the perfect modulation scheme and optimizing the Signal to Noise Ratio. The work also focused on optimal SNR exists for various type of wireless channel.The results show that average energy consumption is minimized and the life time of the sensor is improved.
