Modification of a Sensor Data Management System to Enable Sensors as a Service

Abstract

A modification of a sensor data management system to enable discrete sensor applications. A sensor data control system enables discrete sensor applications to control the configuration, collection, processing, and distribution of sensor data produced by selected sensors at various monitored locations. The sensor service offered by the sensor data control system can be leveraged by any sensor application having an interest in any part of one or more monitored locations.
