Discovering the Sensor Web through Mobile Applications

Discovering the Sensor Web through Mobile Applications Theodor Foerster, Daniel Nüst, Arne Bröring & Simon Jirka LBS 2011 – Vienna, Austria 22 November 2011

Sensor Web 2.0 … is defined as an infrastructure which enables an interoperable usage of sensor resources by enabling their discovery , access , tasking , as well as eventing and alerting … [Bröring et al. 2011]

Discovery in mobile applications OpenSearch REST-based interface Simple API Sensor Web 2.0 Discovery Eventing

Use case – EEA air quality Airbase data description: http://www.eea.europa.eu/data-and-maps/data/airbase-the-european-air-quality-database-3 Source: EEA Air quality viewer - http://www.eea.europa.eu/themes/air/airbase/map-statistics

Requirement – Resource efficiency Minimized communication & processing overhead

Requirement – spatial context

Requirement – temporal context

Requirement – thematic context

Architecture Register, search & access
