Read moretention paid to efficient query processing for aggregate queries [15, 20, 23]. In the TAG system [15], users connect to the sen-sor network using a workstation or base station directly connected to a sensor designated as the sink. Aggregate queries over the sensor data are formulated using a sim-ple SQL-like language, then distributed across
