The wireless sensor network is one of the types of Ad hoc network. Any sensor node can join or leave the network when they want i.e. self-configuring in nature. There is no central controller is present in wireless sensor network. Wireless sensor nodes are responsible for data routing in the network. Wireless sensor network is used to monitor the environmental conditions like, pressure, temperature and humidity etc. Wireless sensor network is deployed in the far places like forests, deserts etc. Wireless Sensor nodes are very small in size and have limited resources. In such far places it is very difficult to recharge or replace the battery of the sensor nodes. In such conditions, the authors focus to reduce the battery consumption of the sensor nodes.
