A Pervasive System Architecture That Supports Adaptation Using Agents and Ontologies

In the context of the EU funded R&D project ATRACO we are developing a conceptual framework and a system architecture that will support the realization of adaptive and trusted ambient intelligent systems. Our approach is based on a number of well established engineering principles, such as the distribution of control and the separation of service interfaces from the service implementation, adopting a SOA model combined with intelligent agents and ontologies. Agents support adaptive task realization and enhanced human-machine interaction while ontologies provide knowledge representation, management of heterogeneity, semantically rich resource discovery and adaptation. ATRACO systems are dynamic compositions of distributed, loosely-coupled and highly cohesive components that operate in dynamic environments.
