Towards runtime adaptation in real-time, networked embedded systems

In this work, we consider reliable runtime adaptation in networked, embedded systems with tight real-time constraints by adapting the placement of software components on a multitude of hardware components. We show the need for a hierarchical transaction concept in this context. In particular, we consider multiple adaptation steps under hard system constraints and also introduce a model with undesired configurations, which cannot be maintained for an extended time period. Furthermore, we discuss implementation issues for such an adaptation process, including the actual task migration implementation, for real-time, embedded systems.
