Approximate Aggregation Techniques for Sensor Databases

tention 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

TinyCasper: A Privacy-Preserving Aggregate Location

This demo presents a privacy-preserving aggregate location monitoring system, namely, TinyCasper, in which we can monitor moving objects in wireless sensor networks while preserving their location privacy. TinyCasper consists of two main modules, in-network location anonymization and aggregate query processing over anonymizedlocations. Inthe rst module, trusted wireless sensor

Aggregate query processing in the presence of

Since the processing of a tumbling window query is the same as multiple invocations of a single window aggregate query, we assume 0 < ℓ < w without loss of generality in the rest of paper. To make our presentation simpler, we also assume that Q w is invoked at timestamp 1 in this section.

Robust Approximate Aggregation in Sensor Data Management

Robust Approximate Aggregation in Sensor Data Management Systems · 5 parents. This process runs continuously and after h steps, where h is the height of the aggregation tree, the aggregate result arrives at the root. In order to conserve energy, sensor nodes sleep as much as possible, i.e. whenever the processor and radio are idle.
