Towards a Framework for Self-adaptive Component-Based Applications

Nowadays, applications must work in highly dynamic environments, where resources availability, among other factors, can evolve at runtime. To deal with this situation, applications must be self-adaptive, that is adapt themselves to their environment and its evolutions. Our goal is to enable systematic development of self-adaptive componentbased applications using the Separation of Concerns principle: we consider adaptation to a specific execution context and its evolutions as a concern which should be treated separately from the rest of an application. In this paper, we first present the general approach we propose and the corresponding development framework and tools we are developing to support it. Then, in order to validate this approach, we use it on a small component-based application to show how it can be made
