Titel
An OGC compliant Sensor Observation Service for mobile sensors
Abstract
This paper presents the design and implementation of an OGC (Open Geospatial Consortium) compliant Sensor Observation Service (SOS), which supports spatial queries for mobile sensors. The work was carried out in the scope of the European ESS project, aiming at the development of a mobile geosensor network for supporting operational management in crisis events. Our sensor web service is complemented by a client programming framework which allows for browser-based access to and visualization of mobile sensors. We demonstrate several use cases, including real-time visualization of mobile sensors, spatial queries and value-based filtering. Our performance evaluation shows that the SOS implementation scales up to supporting more than 1900 sensor observations per second, which clearly outperforms other open SOS implementations.
