Abstract

Distributed multimedia systems have a high-variability of requirements and the most of them can be dynamically changed. So, these systems should provide support for dynamic adaptations in order to adjust their structures and behaviors at runtime. This paper proposes a meta-model for description of self-adaptive distributed multimedia applications, which allows describing models at runtime used to define new structures consistent with the requirements and other involved elements of the system, keeping a system self-representation. The meta-model can represent the system components and their relationships, policies for quality of service and adaptation actions. Further, this paper presents an architecture for the proposal implementation and an ADL defined to model a case study.
