One of the major problem in Wireless Sensor Network (WSN) is the energy consumed by the sensor node. Each node is equipped with battery and used for sensing, computation and communication. Life time of the sensor node depends on the lifetime of the battery. When the sensed data is transmitted over a longer distance, more amount of energy is consumed and leads to frequent node failure and hence the network lifetime is reduced. Recharging or replacing the battery of the sensor node is more tedious in WSN.
