(Submission #154)


Information is at the core of all “Smart” initiatives; a foundation of facts upon which to apply logical reasoning. Through the emergence of the Internet of Things (IoT), this data landscape has been vastly transformed, with information sources pervasively ingrained within objects of our daily lives. The IoT paradigm assigns this information to the “Thing”; the true source of provided information is a sensor embedded within the Thing. The IoT makes vast amounts of information available. While the final goal pertains to Big Data, the sensor actually deals with “Tiny Data”; light-weight devices assaying a value for specific property and propagating this result for further processing. Bridging the gap between “Tiny Data” and the requirements of Big Data is one of the core challenges in enabling a Smart World. IoT Sensors and Smart Energy IoT Sensors are essential for Smart Energy. Regardless of the specific goal, the basic principles of sensors providing information as a basis for automated decision making are ubiquitous from facility management to city wide levels. Through the use of light weight sensor networks, fine grained information is becoming available from sometimes unexpected sources. Standardization allows for scaling from Building Management Systems (BMS) to cross-sectoral District Energy Management Systems (DEMS). Meteorological information is being gleaned not only from automated meteorological stations integrated into other systems or from car sensors. OGC SensorThings API The OGC SensorThings API is an open geospatial-enabled IoT standard geared to overcome the interoperability challenge in the IoT. It can be described as ‘Sensor Web Enablement for the Internet of Things’. SensorThings is designed to interconnect heterogeneous devices, data, and applications through a RESTful application programming interface (API) and the use of JSON as a light-weight means for data encoding. A publish-subscribe-based messaging protocol extension for real-time operations is available through the use of the Message Queuing Telemetry Transport (MQTT) ISO standard. In addition to providing data from sensors, SensorThings can also be utilized to task sensors, as well as to trigger other forms of actuators. Within INSPIRE, the observational community is analyzing the potential of utilizing SensorThings within the context of download services for observational data. While this work is ongoing, no blocking points hindering the adoption of the SensorThings as an INSPIRE download service have been identified to date. The DataCove demonstrator utilizing the Fraunhofer IOSB FROST Implementation of SensorThings currently powering various real-world monitoring and control applications will be presented.
