A context-aware system for smart home applications

Context-awareness is an important part for ubiquitous computing. Many applications of ubiquitous computing have to access some related contexts in order to provide the fight services at the fight time and the right places. However, there are some challenges for applications in ubiquitous computing, especially for those in smart home. These challenges make the design of smart home applications much more difficult than other applications. Therefore, we propose a context-aware system, CASSHA (Context-Aware System for Smart Home Applications), which is designed for smart home applications. CASSHA consists of the components for processing, representation, provision, and coordination, and is able to provide required contexts for smart home applications without conflicts. The system overcomes most of the technical challenges for smart home applications, and satisfies the requirements for these applications.
