Wireless sensor networks (WSNs) consist of many sensor nodes. WSN are widely used in applications like habitat monitoring, disaster management, security and military, etc. Wireless sensor nodes have limited processing capability with very low battery power. This restriction of low battery power does not allow the sensor nodes to be alive for longer time. Therefore energy conservation has to take place. In this context Data aggregation technique is used. It is the process of aggregating of data and sending to the base station. Hence it reduces the number of packets to be sent to sink. Data aggregation technique increases the network lifetime by reducing the energy consumption.
