Abstract

Some aspects of the mobile environment, like lower bandwidth and higher error rates, can affect distributed applications that have real-time requirements. In order to maintain the quality of service expected by such applications, a middleware platform can monitor its execution environment and perform dynamic adaptations on its structure and behavior. To do this, the middleware must know which QoS attributes affect the application and act in accordance with policies described in a specific language. In this paper we propose a self-adaptive architecture, based on the Meta-ORB approach, which uses adaptation policies described in the same modeling language used for the definition of middleware configurations. The paper also presents a study on the use of this architecture for applications based on digital ink.
