IoTMoF: A Requirements-Driven Modelling Framework for IoT Systems
Paul Boutot, Sadaf Mustafiz · 2023
The engineering of IoT systems brings about various challenges due to the inherent complexities associated with such heterogeneous systems. In this paper, we propose IoTMoF, a model-driven framework for requirements development, design and code generation of IoT systems. IoTMoF supports platform-independent modelling (PIM) with the ReqMIoT environment, which covers use case modelling and generation of IoT ARM compliant domain models. The use case model addresses exceptional behaviour by specifying exceptional situations along with handling functionality. The PIMs are mapped to platform-specific models, namely an IoT information model and a statechart model. The statechart defines both normal and exceptional behaviour of the system. These models form the basis for the subsequent generation of code for the IoT platform. A configuration model containing details of the IoT devices is used to generate wrapper code for deployment. Our work is demonstrated with the use of a smart lights system.
