Collect Sensor Data - an overview | ScienceDirect Topics
www.sciencedirect.com › collect-sensor-dataWhen a data query collects sensor data in the past and STDB can provide enough data, collected data are processed on the Chronus server. Otherwise, a QA visits sensor nodes, collects sensor data, processes them on the last node of its route, and returns the result to a Chronus macro-program. This in-network data processing saves the power consumption in a sensor network by reducing the amount of data to exchange between nodes.
