Wireless Sensor Network (WSN) is an emerging and new technology in the field of data processing and wireless communication. The wireless network is composed of tiny nodes called as sensor nodes which are battery powered and are capable of transferring information to the destination i.e. Sink. Being battery powered these nodes are limited in energy and loose the energy during the process of routing. Once the sensor node has lost all its energy, it is dead. With the death of first sensor node the network becomes unstable.
