A novel model using Reo for IoT self-configuration systems

The new technologies have influenced the world we live in, it is becoming more and more connected; every thing, every object it contains has a virtual image in the digital world. Which also changed the vision of developers towards the Internet of Things, developers spend their time improving their software by adding new features offered by the new connected objects. Therefore the applications must change it behavior in order to be adapted for the new update. Developers spend an important time adapting their applications, reusing or rebuilding new module-based applications, either by composing or by directly reusing modules. These updates depend on the context and nature of this application. Usually, to update an application, we must stop, modify, recompile and restart the application. There may however be cases where this traditional maintenance process can not be applied to certain categories of applications, in which a complete service interruption can not be tolerated. These applications, described as ”non-stop”, must be dynamically reconfigured with minimal disruption. To solve this problem, we propose a system reconfiguration module in real time. Our model is based on a component approach. In this paper, we assume that components are the smallest entities in any system. We summarize the dynamic reconfiguration of a system by automating the disconnection or connection (direct or via an adapter) of components. The new configuration allows the system to achieve its objectives and ensure its proper operation under various conditions imposed by the environment.
