Managing an Integrated Ubicomp Environment Using Ontologies and Reasoning

One issue hindering the deployment of integrated ubicomp environments is the lack of a shared model for applications to utilize resources across administrative and network domains. Through the use of concrete examples, we describe our proposed common model for ubicomp environments to address this issue. We then present use cases and additional examples for how our ubicomp common model (UCM) is used by our integration framework. The ubicomp integration framework (UIF) uses an ontology driven architecture (ODA) (P. Tetlow et al., 2001) and enterprise application integration (EAI) techniques to integrate existing ubiquitous computing middleware to the common model. The use cases illustrate how the integrated model and reasoning is used to maintain a dynamic integrated model of an environment
