Context as autonomic intelligence in a ubiquitous computing environment

: This paper presents the ANS architecture that uses ubiquitous computing to monitor medical patients in the home. Since there is no notion of the patient carrying out maintenance of such a system, it must be self-managing or autonomic. In the ANS sensors, such as temperature, location, etc., use a form of logic to abduce a context, i.e. the state/quality of a given device or its function. Our contribution lies in the emergent autonomicity of the architecture driven by its ability to derive the most appropriate source for a particular application. This is done by allowing the application to define mathematically its own notion of what level of service provides the best satisfaction and is based on Quality of Context attributes that describe each alternative. These applicationspecific definitions allow the ANS to optimally adapt to alternative sources when context providers fail or their quality changes. Further, we uniquely evaluate the trustworthiness of the different sources of conte...
