    In this paper the Fraunhofer ESK presents in cooperation with CEA LIST a novel integrated model-driven methodology for developing selfadaptive distributed embedded systems. Software components of the design model are enriched with self-descriptions which provide information at runtime that is necessary for adaptation decisions. Therefore, a new self-x profile and the tool-chain with the essential model transformations are introduced. The iterative development process, including early feedback through an integrated simulation framework, enables an early refinement of the self-adaptive system.

    Increasingly distributed embedded systems are deployed in complex scenarios and must be able to adapt to changing environments and internal system changes. Such self-adaptive embedded systems pose great advantages in terms of flexibility, resource utilization, energy efficiency and robustness. The realization of these systems require enhanced development methods to incorporate the adaption to the design. We introduce a novel concept for the model-driven development of self-adaptive embedded systems. The focus of our work is the definition and transfer of the information needed for the adaption runtime. This is preserved as so-called self-description of the components. We present our self-x profile, a modeling extension for describing the adaption, and the respective design flow with built-in transformations. Furthermore, we outline the applicability of our methodology in an automotive use case.
