Dynamic adaptive software components: the MOCAS approach

While software adaptation is recognized as an important challenge of software engineering, this discipline is still in its infancy. Adaptation must be prepared at design time to be observed at runtime. In this context, important efforts are required on software architectures to endow them with adaptation potentialities. In this paper, we propose a component-based software development approach, a component model especially, to create an adaptation support at runtime. We implement the inside of components by means of UML 2 State Machine Diagrams. By using model executability, we detail in the paper how to carry out dynamic adaptation of software components.
