Data aggregation is a process in which information is gathered and expressed in a summary form. The aggregators collect data from a subset of the network and aggregate the data using aggregate function. Data aggregation in wireless sensor network refers to acquiring the sensed data and communication capabilities from the sensors to the gateway node. Restrictions involved in WSN are power consumption requirement, life time of network, data integrity, and confidentiality. So these restrictions are solved using data aggregation for power consumption and lifetime.
