Wireless Sensor Networks (WSNs) are deployed to capture the sensed data from tiny sensors spread around the physical environment. In general, WSNs are used to monitor physical phenomena like temperature, pressure, humidity etc. In most of the cases they are deployed in remote geographic locations and operate unmanned. Usually, these sensors are battery operated. Due to these deployment circumstances, battery recharge or replacement becomes almost impossible. Hence, the foremost requirement of any WSN is to utilize the battery power in an efficient way. A sensor node expends most of its energy in data transmission.
