Enabling Self-adaptivity in Component-based Streaming Applications
Special Issue on the 2nd International Workshop on Adaptive and Reconfigurable Embedded Systems (APRES''09)
Self-adaptivity is the capability of a system to adapt itself dynamically to achieve its goals. By means of this mechanism the system is able to autonomously modify its behavior or the way in which applications are run and implemented to achieve the goals set.In this paper we propose a framework that uses a component-based approach to implement self-adaptivity at application level. By using this mechanism, the framework provides the ability to perform both adaptation on the structure of the application (i.e., how the components are connected together) and on internal parameters of each component. At application level, there is a mechanism to monitor different parameters and to check whether the system is meeting the assigned goals or not. A controller drives adaptations when goals are not met.
