Description: The project 'Flexible and Efficient Integration of Sensors and Sensor Web Services' (NRW.IKT – Sensor Web) is funded by the European Regional Development Fund (ERDF) for NRW (contract number N 114/2008) of the European Union. It is a joint project with the Institute for Geoinformatics (IfGI) of the University of Muenster and aims at facilitating the integration of geosensors into the Sensor Web.

One core element of this project is the SensorBus, which establishes an intermediary layer between geosensor networks and the Sensor Web to close the conceptual gap between these two distinct layers resulting from different protocol stacks and data models. Thereby, the Sensor Bus facilitates the integration of new sensors as well as new sensor web services. Our aim is to enable true plug & play of sensor and service adapters to minimize the efforts of adding new sensors or services to the Sensor Web. It will allow sensor vendors to easily plug-in sensors so that they are subsequently available on the Sensor Web. Service providers benefit, since they can support a wide variety of sensors by adapting their services to the Sensor Bus.

Another important element is the Sensor Interface Descriptor (SID) concept, which is based on OGC's Sensor Model Language (SensorML). SIDs can be used to describe the protocol of a sensor. A sensor's SID instance enables a SID interpreter to translate between the sensor's communication protocol and the SWE world. Once a sensor interface is described, the SID interpreter can work with it and is able to connect it with Sensor Web services (e.g., SOS or SPS). From then on, the sensor's functionality can be accessed in an interoperable way. The SID approach is particularly beneficial for sensor manufacturers who don't have to change their sensor's protocol or adapt their sensor interfaces to standardized approaches such as IEEE 1451. Instead, an additional interface description, the SID, enables the sensor integration with enterprise systems. Once a sensor interface is described by an SID, it can be used in multiple applications and systems by different user communities.
