The pervasiveness of smart appliances in the home, the increase of computational power of traditional home appliances, and the widespread adoption of wireless networking are creating a unique opportunity in domotics. The challenge lies in moving from a set of isolated devices towards a network of home appliances interoperating and scaling seamlessly to provide services to the home user. The major barriers to achieve this is the abundance of non-interoperable domotics standards and the lack of a generally agreed architecture. We propose a service-oriented architecture (SOA) for the interaction of home appliances and the creation of value added services based on standard web services. In particular, we propose the use of WS-Notification as the basic layer for device interoperation. We have experimented the proposed architecture in the context of a project for the assistance of the elder citizen. We provide preliminary results for the case of fall-detection. Addressing the operability of different sensors yields, for the first time, to an integrated and scalable system that detects falls by fusing data transported via a truly vendor-independent publish/subscribe mechanism.
