The tremendous increase in the Wireless Sensor Network (WSN) in the last decade has increased the potential applications including environment monitoring, smart spaces, medical systems, and robotics exploration. Sensors integrated into structures, machinery, and the environment has led to fewer catastrophic failures, conservation of natural resources, improved manufacturing productivity, improved emergency response, and enhanced homeland security. Further the communication between the nodes consumes higher quantum of battery power. Battery is the prime source for Wireless Sensor Node to function. Hence every aspects of sensor node are designed with energy constraints.
