Outline of the Presentation • OGC Sensor Web Enablement • Sensor Web Vision • Sensor Web Interoperability • 52°North SWE ØWorking Group ØServices • 52°North SWE in Action • 52°North‘s Client Solution • Move Strategies • Conclusion J. Echterhoff http: //www. 52 north. org 3

OGC Sensor Web Enablement • Motivation: lack of a generic framework for sensor data integration into SDIs • Goal: make all kinds of sensors Ødiscoverable Øaccessible Øcontrollable via the WWW • Framework for a WWW-based sensor web • Foundation for “plug-and-play” web-based sensor networks J. Echterhoff http: //www. 52 north. org 4

Movement Strategies • Mobility improves performance of sensor networks • Movement strategies define sensor mobility behavior • Adaptation to phenomenon characteristics necessary J. Echterhoff http: //www. 52 north. org 17

Conclusion • 52°North‘s SWE WG is pushing forward to realize the Sensor. Web vision • Implementations are available for current OGC SWE services • additional implementations will be available in the future to reflect the most recent specifications • find additional information at: https: //www. incubator 52 n. de/twiki/bin/view/Sensornet/ Web.
