In wireless sensor networks, the sensor nodes are capable of collecting, sensing and gathering data from environment. In recent years, the use of Wireless Sensor Network (WSN) has been tremendous increased in various fields such as military, environmental, medical, home monitoring and disaster management. In such applications large numbers of nodes are deployed, these nodes work independently and often remain unattended. These nodes sense the data from the environment and communicate the same to the sink or base station.
