In ubiquitous computing systems, applications must be able to respond to dynamic context changes in order to maintain collaboration between entities. A promising solution consists of developing context aware applications which automatically change their behavior according to the user needs, the available resources and the surrounding environment. Furthermore, a context aware application is characterized by a closed feed back loop with four phases: Monitoring, Analysis, Planning and Execution. In this paper, we focus on the second phase and we propose an analysis approach of collaborative ubiquitous systems which aims at analyzing context information and detecting significant abnormal changes. The proposed approach relies on thresholds in order to track down context changes. Once relevant context changes occur, the context aware application will be notified to trigger its suitable process dynamically in order to deal with the changes.
