Wireless sensor network is a promising technology that plays a vital role in various applications i.e. disaster management, battle field surveillance and monitoring applications. It is especially useful in catastrophic or emergency scenario where human participation may be too dangerous. The sensor networks have evolved over a period of time. The failures are inevitable in wireless sensor networks due to inhospitable environment and unattended deployment; therefore sensor nodes must operate potentially in large numbers. The latest generation of sensors encompasses self organizing, flexible and scalable networks.
