Ubiquitous computing environments are highly dynamic due to changes in the set of available resources and also because of changes of user’s demands in different operational contexts. Thus, applications for these environments require dynamic-adaptation support mechanisms in order to meet requirements that vary along their operational time. In this paper we present dynamic-adaptation support mechanisms based on technologies that are widely available and adopted by real world product developers. Some experiments demonstrate that the proposed mechanisms meet performance and flexibility requirements that are essential for the implementation of real pervasive systems. |
