Context-aware services based on OSGi for smart homes

Recently, context aware service has become one of the most promising topics for ubiquitous computing. In this study, we focus on developing a context aware framework based on the OSGi model to automatically provide appropriate information and services for users in a smart home environment. A middleware for integrating home services through a reasoning system is developed. By using JESS Markup Language (JessML), the semantic information of contexts can be easily described, shared and reused. Also, Java expert system shell (JESS) is used for automatically reasoning adaptive services for users. Experiments performed with the developed prototype system show that the proposed framework can automatically provide appropriate context aware services for users in a smart home environment.
