Data aggregation in wireless sensor network refers to acquiring the sensed data from the sensors to the gateway node. Data aggregation plays a vital role in wireless sensor networks since the aggregation schemes followed here involve in reducing the amount of power consumed during data transmission between the sensor nodes. There is several aggregation techniques followed in wireless sensor network, such as tree based aggregation and in network aggregation. A Wireless Sensor Network (WSN) typically consists of a sink node sometimes referred to as a base station and a number of small wireless sensor nodes.
