2 Agenda Introduction Scenario Requirements & Related works System Architecture Summary

3 Mobile devices Sensors & Actuators Web Services Existing solutions – Not generic – Need IT knowledge MERCURY Introduction Internet of Computers

4 Scenario B J

5 Requirements

6 User Interface Combine sensors, services, and actuators Easy-to-use No programming Mashup builder Web Portal IBM Mashup Center SensorMap Websphere Portal

7 User Model User authentication User preferences http://www.minerva-portals.de/

8 Discovery of Devices & Services Functional and non-functional properties Ontologies to classify sensor Heavy-weight matchmaking algorithms Web service for social networking Connects sensors with users and applications ObservationObservation SensorSensor TimeTime LocationLocation WeatherWeather Working Group on Semantic Sensors Sensorpedia

9 Rights Management Which sensors/actuators can be access by whom Which level of granularity of information ConServ - Context as service management – Sharing of context data across environments – Discovery of remote context data – Privacy protection of context data Heterogeneity of sensors Available for non-IT users

10 Sensor Integration Heterogeneity Scalability Middleware Web-based query interface Handle sensors of all types Middleware Web-based query interface Handle sensors of all types GSN - Global Sensor Network Internet Sensor node GSN Wikipedia of sensors Sensor querying and tasking SensorMap Wikipedia of sensors Sensor querying and tasking SensorMap SenseWeb
