IoTA-MD: a model-driven approach for applying QoS attributes in the development of the IoT systems

This paper presents IoTA-MD, a model-driven approach to instantiate the IoT-A Reference Architecture and manage QoS attributes in the early stages of IoT system modeling. It uses the principle of Separation of Concerns (SoC) to address complexity issues of the IoT system development considering both vertical and horizontal perspectives. The horizontal SoC is addressed by handling quality attributes separately from the Domain and Information models. The vertical SoC is addressed by using MDA to design the system models with the appropriate abstraction level, and its transformation artifacts to refine such models from an abstraction level to other. Moreover, the IoTA-MD provides a modeling tool to facilitate the design/maintenance of the IoT-A models at the CIM and PIM levels.
