The system architecture for self-organizing smart home ecosystems must fulfill the standard requirements of measuring home conditions, processing instrumented data, and monitoring home appliances as well as providing self-configurations mechanisms for the sensors and actors forming the ecosystem. The communication framework should allow devices to discover counterpart devices, discover the services they offers, invoke these services when needed and get notifications about the state changes of their cooperation partners. Our approach takes advantages of the communication framework OPC UA, since it provided a set of prebuild services, which can be adapted to our needs. The following lines describe the OPC UA communication framework first and describe the architecture of our communication model secondly.
