An architectural model for building distributed adaptation systems
Résumé
Dynamic adaptation allows the modification of an application configuration at runtime, according to changes in the environment and/or in users' requirements. The case of adaptive distributed applications has not been addressed substantially. In particular, the distribution of the adaptation system itself has been rarely considered. We address this issue by proposing an architectural model of distributed adaptation systems. Our model allows dynamic adaptation management in a distributed and coordinated manner and expresses variation points of the system. In this paper, we present our model and its use to build distributed adaptation systems. We have applied our results to build an adaptive distributed data replication system used in a medical environment dedicated to remote health care delivery for patients at home.
