The SAMBA (Systems for AMBient intelligence enabled by Agents) architecture reported here is a conceptual service-oriented architecture supporting the interaction and interoperability of systems, applications and actors by the notion of an “Ambient Intelligence Element Society”. The objective is to provide an ecosystem infrastructure supporting the interaction and interoperability of various elements by encapsulating and representing them through agents acting as members of an Ambient Intelligence Elements Society, and by using executable models at run-time in support of interoperability.
