Research Topics
My main fields of interest are concentrated on distributed adaptive software. These kinds of applications are composed of many distributed ineracting software entities, must undergo various modifications (at both architectural and behavioral levels) during their execution in order to respond to new user's requirements or to changes in their execution context. These new requirements introduce a complexity resulting from an abundant interaction between the distributed software entities and of the dynamics of their software architecture. The strong presence of this software in several critical sectors, such as the financial sector, the medical sector, and the public transport sector, requires their reliability. Thus, our objectives are to provide environments that provide support and assistance for dynamic managing (at runtime) of the adaptive distributed software allowing to master their complexity and to ensure their reliability. In order to achieve this, we are seeking to develop models, mechanisms for designing, and managing adaptive distributed software. The implementation of these applications considers various software technologies, such as the object, the component, and Web services, and target various material platforms, such as wireless sensors, grid of computers, etc.
In our work, we proposed methods, for describing and managing dynamic software architectures, based on formally provable visual models in order to preserve QoS.
