Wireless sensor networks have created new opportunities across the spectrum of human efforts including engineering design, forest fire tracking, and battlefield surveillance. Wireless Sensor Network is a group of sensor nodes that comprised of sensing, computing, and communication elements that gives an administrator the ability to observe and react to events and phenomena in a specified environment. Basically, sensor network have mainly two types of applications: monitoring and tracking. In monitoring, air pollution monitoring, traffic monitoring etc and in tracking, animal tracking in habitat consisted. When the sensor nodes are deployed to develop a wireless sensor network there must be routing of data to communicate with other nodes and conserve the battery power and increase the network lifetime.
