Query Privacy Preserving for Data Aggregation in Wireless …
The main roles of aggregation nodes are to store the sensing data and reply the queries received from BS. If most of the aggregation nodes have been compromised successfully, the data of whole network may be revealed and tampered with easily. This may result in serious threat or economic loss, even the damage to the safety of state property.

In this paper, we propose an adaptive in-network aggregation operator for query processing in sensor nodes of a WSN, called ADAGA (ADaptive AGgregation Algorithm for sensor networks). The ADAGA adapts its behavior according to memory and energy usage by dynamically adjusting data-collection and data-sending time intervals.
