Abstract
We propose an approach based on runtime models and Aspect Oriented Software Development for modeling and implementing dynamically adaptive systems. Such system requires specific modeling formalisms to support the definition of the monitoring and reconfiguration modules at an abstract level. The verification of the consistency during the reconfiguration is also an essential and primordial task in the development process of dynamically adaptive systems. In addition, a middleware that enables to perform the dynamic reconfiguration during execution should be implemented.Our proposed approach addresses these requirements: It enables specifying dynamically adaptive systems using AADL and AO4AADL and verifying the integrity of the system at any time of its life cycle even at runtime based on a set of architectural patterns. Our approach uses the Aspect Oriented Software Development to ensure the monitoring of the system and perform the reconfiguration through a set of routines developed in our middleware.
