    layer for sensor networks; we call the component of the system that is located on each sensor node the query proxy. Architecturally, on the sensor node, the query proxy lies between the network layer and the application layer, and the query proxy provides higher-level services through queries.

    In addition, when the sensing areas of sensor nodes are disjoint, the coordinator of each sensor becomes itself and we perform traditional aggregate query processing. Thus, the problem we are considering is a generalization of the traditional in-network aggregation problem.

    Sensor network applications rely heavily on aggregate queries. Queries are also considered a natural way for users to interact with the sensor network [23]. Therefore, several studies have been carried toward (aggregate) query processing in sensor networks [20,21,23]. The common approach to query processing in sensor networks has two phases.
