Services discovery and composition in Intelligent Environments for mobile devices

Since the latest years, residential automation has been becoming a very discussed and recurrent subject. Part of such success is given by the meaningful diffusion and offer of portable electronic devices, with great power of computation, low energy consumption and, mainly, high level of connectivity. Joining the residential automation, the term ldquointelligent environmentsrdquo (IE) has been being defined, which brings a paradigm change, not considering the fact of just controlling devices, and leaving for a world where these are aware of everything that surrounds them. This paper proposes an architecture on management of services in IE for mobile devices, such as PDAs, cell phones and smart phones. The proposed architecture has three main characteristics: (i) discovery and remote composition of available services in the IE; (ii) adaptation of services and functionalities according to the userpsilas profile, using security policies with different levels of accessing the system; (iii) flexibility in the insertion of new residential automation devices, adding, dynamically, services to the IE. The architecture validation is presented through a case study which utilizes as scenery an automated seminaries room.
