2. What is OpenSensorHub? OpenSensorHub is a collaborative open source project aimed at developing software to allow anyone to easily build smart and scalable sensor networks interconnected through OGC® sensor standards Objectives: –Implement full OGC SWE vision –Hide the complexity –Make it easy (to deploy, to develop new sensor drivers) –Allow efficient live data streaming and stream processing –Support multiple computing platforms (from embedded to Cloud) –Not limited to SWE (SensorThings API, MQTT, etc.)

3. OGC Sensor Web Enablement (SWE) SWE = sensor, actuator, and process interoperability and integration Supported functionality: –Getting data … from ANY type of sensor –Tasking … ANY type of sensor or actuator that accepts commands –Receiving alerts … from ANY type of sensors or process –Robust metadata … about sensors and their measurements (provenance) –On-demand processing … within and between nodes Version 2.0 (SWE Common, SensorML, O&M, SOS, SPS) is the result of more than 10 years of collective thinking and is very mature

5. Deployment Platforms

6. OpenSensorHub on Android phone

7. Video SensorHub using ARM/RPi

8. Why OpenSensorHub? The SWE design is sound and several implementations of SWE services are in operation around the globe (but too few) Starting from scratch, SWE is still too hard to implement and deploy There is a strong need for open-source software that –is fully SWE-compliant and implements the full vision of SWE 2.0 –is efficient, modular, and scalable –most importantly, is easy to deploy and configure with very little or no software development The success of GeoServer serves as a model and incentive for the proposed project

9. OpenSensorHub = Open Source Java software to make it easy to: Connect ANY sensor/actuator/process and store/view the collected data Deploy standard web services (OGC ® SWE) To access archive data and/or live sensor data streams To send commands to sensors and actuators Interconnect SensorHub instances Via classic HTTP services and web sockets Via P2P networks Via IoT protocols Connect to other mapping servers (e.g. Geoserver, KML) Allow configure via a Vaadin-based web UI Enable on-demand processing within SensorHub What does OpenSensorHub do?

10. Web-based Configuration Interface

12. On-Demand Processing (SensorML v2.0)

13. On-the-fly Processing OpenSensorHub enables on- demand processing of observations in SOS Processed observations then become additional outputs of the system Processing can be included during configuration or pushed to the node using SensorML encoding Processing is also enabled for SPS allowing more intelligent tasking (using geospatial awareness for example) The process on the right provides on-demand georectification of video

15. Client components for mapping

16. Client components for streaming data

17. Synchronizing streaming data

18. Two approaches for getting measurements from OSH-SOS getObservation – decent for “Products” Returns O&M – XML Lots of metadata about the measurement Not necessarily efficient for tuples, large, or streaming data getResult / getResultTemplate – highly efficient !!! Typically call getResultTemplate first but only once Returns SWE Common description of record and encoding example Call getResult to open a data stream/block or get latest values Returns values only (e.g ASCII CSV or binary) example Accessing Measurements

21. Current Directions Real, persistent and mobile-deployed systems Working with several federal and local agencies on OSH extension and real deployment Appliance (i.e. “device”) design and development Client support Dynamic/mobile deployment emphasis Small “stick” or “drop” technology (e.g. sticky-cam, drop air-quality station) Local communication (e.g. Serial, USB, BlueTooth LE, ZWave, even SPI, I2C) New device discovery API for Immediate discovery of newly deployed sensors and nodes Local storage push to cloud OpenSensorHub Security BasicAuth, OAuth Deeper permission/role-based a22uthorization Encryption – Full path: sensor to cloud Antispoofing, DoS protections Easing introduction of new sensors Libraries (e.g. communication protocol support, Arduino library) Spec-Sheet look SensorML viewer/editor Auto generation of drivers using SensorML Editor

22. Relevance This effort is vital to any organization that needs to: Bring sensor observations into your geospatial Common Op Picture Achieve interoperability across disparate sensor and sensor processing systems Enable workflows and cross-cueing across Multi-INT or multi- phenomenology systems Re-purpose various sensors and actuators in a variety of different orchestrated workflows, rather than slaving them to an individual stove- piped sensor network. Support on-the-fly reconfiguration of systems and processing to adapt to ever-changing operational environment and observable phenomenon. Deploy SensorHub nodes quickly, without generating new and costly engineering projects.
