The major challenge in designing the Wireless Sensor Networks (WSNs) is to reduce the power consumption of each sensor nodes and thereby increasing the network lifetime. WSN has variety of applications in medicine, manufacturing, health monitoring, military, etc. Sensors have the ability to collect data about surrounding environment, processing the data and transmitted these data to nearby sensor nodes and finally it reaches the sink node through these sensor nodes. Sink is also be a sensor node which collects the data from other sensor nodes in WSN, process the data and send them to the user through internet. The main problem in wireless sensor network is their lack of energy supply.
