Abstract:Ubiquitous computing has gained considerable popularity in recent years due to the proliferation of mobile devices like laptops, mobiles phones and pocket computers. An emerging field in this regard is providing users with context-aware applications that are able to adapt themselves to their situations. The benefit of context-aware applications like smart homes is that they are able to sense information about the user’s environment and react automatically based on the input that they receive. This allows the application designer to provide users with newer and better services. Unfortunately the distributed nature of participating entities when combined with the requirements for gathering/sensing, storing, advertising and accessing contextual information had lead many developers to believe that a broad deployment of context-aware applications requires a supporting infrastructure. A novel proposal of such a supportive platform is the Context Aware Component Infrastructure (CACI) which aims to assist application developers by abstracting from the details of where and how the context aware information is acquired. The developer only needs to indicate what type of information he/she requires and CACI will do the rest. In CACI terminology sources that provide the context information are called ‘context producers’ whereas applications that use this context information are called ‘context consumers’. Since CACI is still a work-in-progress, in this thesis we present our work on two outstanding issues related to CACI
