Abstract
Ubiquitous communicating systems have particular characteristics, such as their dynamic nature and the great number of users and heterogeneous devices involved. In our work, we focus on collaborative activities. For such activities, users are organized into groups and communicate in order to achieve a common goal. Therefore, the problem of designing and implementing collaborative applications on top of ubiquitous communicating systems is a complex task that requires adequate modeling. In our view, addressing this problem needs a model-driven approach in order to ensure the coherence and correctness of the built systems. In this paper, we propose a multi-level modeling approach for collaborative ubiquitous systems. Moreover, relevant abstraction levels are identified and means are provided for inter-level model transformation (refinement) and for adaptation to context changes (selection). This adaptation is guided by both high level requirements and low level constraints.

Abstract
Service provisioning is a challenging research area for the design and implementation of autonomic service-oriented software systems. It includes automated QoS management for such systems and their applications. Monitoring and Measurement are two key features of QoS management. They are addressed in this paper as elements of a main step in provisioning of self-healing web services. In a previous work [1], we defined and implemented a generic architecture applicable for different services within different business activities. Our approach is based on meta-level communications defined as extensions of the SOAP envelope of the exchanged messages, and implemented within handlers provided by existing web service containers. Using the web services technology, we implemented a complete prototype of a service-oriented Conference Management System (CMS). We experienced our monitoring and measurement architecture using the implemented application and assessed successfully the scalability of our approach under the French grid5000. In this paper, experimental results are analyzed and concluding remarks are given.
