LearnSens (FR-TI1/332) (2009-2011) developed self-learning layer to receive measurements from the sensors and the recognition of unexpected observations that can be a signal of “emergency (nonstandard) state.” Services are based on “Open Source”. LearnSens was oriented to managing and evaluating measurement and sensor-based ambient intelligent features such as dynamic analysis and adaptability, awareness of context, autonomy and interoperability. Interoperability is ensured through standard Open Geospatial Consortium Sensor Web Enabling (OGC SWE). For subsequent data processing are designed database corresponding to the current standards and recommendations of the OGC and SWE for collecting.
