Abstract
Ubiquitous computing environments provide a wide range of new perspectives in Computer Science. Among these, the dynamic collaborative activities carried out by groups of users present particularly complex issues. The highly dynamic nature of such activities, along with the heterogeneity of devices and communication systems, requires adaptive software solutions. In this paper, we propose a multi-layer modeling of system architectures in order to address this problem. This is necessary for taking into account both high level requirements and low level constraints. Moreover, this approach allows adapting the system architecture to handle context changes. We consistently handle inter-layer adaptation actions by considering a lower layer architecture as a refinement of an upper layer architecture. First, modeling layers for collaborative ubiquitous systems are provided. Then, we detail an implementation using OWL and graphs for models and rule oriented techniques, such as SWRL and graph grammar productions, for refinement. Finally, we consider a scenario on board of urban bus fleets as a case study from the more general group collaborative systems to which our models and procedures apply.
