Using the Connected Home Platform to support user tasks as orchestrations of smart objects services

The ATRACO project uses the ambient ecology metaphor to conceptualize a space populated by connected smart objects and services that are interrelated with each other, the environment and the people. User activities are supported by the implementation of ubiquitous computing applications deployed over this ambient intelligence space. In this paper we present a possible realization of the ATRACO vision using the Connected Home Platform, a commercially available system adopted and evolved by ATRACO in order to provide network adaptation and context-aware services. A flexible and distributed context-aware service model is introduced using the OSGi and UPnP frameworks. UPnP is used to unify the existing network infrastructure comprising of heterogeneous technologies and protocols at the IP level. Furthermore, we introduce a context-aware service model and provide an example of orchestrating context aware services with the support of the platform
