Pervasive or ubiquitous computing, proposes the integration between the information and communication technology with the actions and common behaviors presented by people. One of the challenges that it imposes to the environmental automation systems developers, specially building automation developers, is that this integration is processed in such a way that people do not realize they are interacting with a computer, thus its presence becomes omnipresent. Besides the need of an easy and natural interface, there is also the need to incorporate the sensitive computing context to the automation systems. The current control networks utilized in automation systems, building, home and industrial control do not show resources that support the requirements of pervasive computing. This research intend to improve the knowledge associated to modern automation systems, based on LonWorks® control networks, viewing to make them more easily usable as ways to implement pervasive environments. For that, a dynamically settable relationship model was proposed between the intelligent devices of a control network, which allows providing some foreseen characteristics on pervasive computing in a distributed automation system. A LonWorks® technology object model extension is proposed, using middleware concepts, in a dynamic way, to modify behaviors when new situations are identified. The proposed extension was experimentally applied to a few use cases, aiming at its validation and refinement, such as the internal communication of a company, which replaces the usual PABX, which was considered in greater detail. The impossibility of its implementation was found with the current technology, without the use of the proposed extension. Those cases were evaluated and discussed, contributing to a new automation system concept technology that can support provided proposals on pervasive computing.
