The wireless sensor network is the type of ad-hoc network. Wireless sensor network is self configuring network. Any sensor node can join or leave the network when they want. Wireless sensor network is used to monitor the environmental condition like pressure, temperature etc. In wireless sensor network number of sensor nodes are deployed. Wireless sensor network is deployed in far places like deserts, forests etc. Sensor nodes are very small in size and have limited resources. It is very difficult to recharge or replace the battery of sensor nodes at far places.
