Like many other fields, application construction in ubiquitous computing is done by reuse of available software entities. For reasons of conductivity, breakdown, battery charge, but also many others reasons, the availability of these entities is unpredictable. As consequence, the self-adaptation of applications becomes necessary. This requires the specification of parallel adaptations by experts from various fields. This parallel specification can cause interference problems when several adaptations are composed. In this thesis, using graph formalism, we contribute to the definition of a formal approach for the detection and the resolution of interferences. The specification of adaptation uses connectors in order to assemble software entities. Graph rewriting rules are defined to solve the detected interferences. This resolution is guided by the knowledge of defined connectors. In addition, in order to extend dynamically and automatically our interference management mechanism, we propose behavioral modeling of these connectors. This allows us extending our mechanism without an a priori knowledge of connectors and allows afterwards to extend the set of available connectors used for adaptations' specifications.
