System architecture for context-aware home application

Recently, there are many efforts to build ubiquitous computing applications in many projects. The applications have covered areas such as home, office, and mobile. However, it tends to make ubiquitous system not based on scenario, but technology. In contrast, we firstly define targeted application at home such as u-media, u-healthcare, u-control and u-management scenarios. We focus on implementing context-aware home application. From these applications, we abstract technologies and system architecture required to be developed. We define the system architecture in order to easily accommodate context-aware information and to support new application.
