An Architecture-Based Framework for Managing Adaptive Real-Time Applications

Real-time systems are increasingly used in dynamic changing environments with variable user needs, hosting real-time applications ranging in number and nature. This paper proposes an architecture-based framework for managing components' dependence and lifecycle in an effective and uniform way. A real-time component runtime service is proposed here to maintain the global view, control the whole lifecycle of the components and keep existing real-time components' promised contracts in the face of run-time changes. This framework is designed to be easily extended with other constraint resolving policies as well as dependence descriptions languages. At end of this paper, the framework is tested by a simulated control application via adaptation and performance aspects.
