Smart Object Cooperation through Service Composition

We consider the coordination of smart objects interacting in physical environments. We show that it is possible to re-use the concepts related to the Service Composition paradigm to support the coordination of smart objects such as for example household electrical appliances, sensors, actuators, smartphones, etc. We show that applications involving smart object interaction can be seen as a particular case of event driven composite services. As a consequence a platform supporting smart object interaction can be obtained by including additional components to an event driven service orchestration platform. In this paper we describe a platform for smart object interaction based on a platform for event driven service orchestration enriched with two additional components, namely a Presence Server component, to manage smart object availability, and a Universal Gateway, to support smart object interoperability.
