The Future of IoT Software Must be Updated

International audienceDecades of software engineering shows that updating deployed software is not a nice-to-have, but a must-have. Deployed software (e.g. an IP protocol stack) is never bug free, and these bugs must be patched to increase its robustness and security, and as communication standards and application logic evolve, deployed software typically needs to evolve in parallel. As the IoT emerges, the same will apply to deployed IoT software

Towards a Model@runtime Middleware for Cyber Physical Systems

International audienceCyber Physical Systems (CPS) or Internet of Things systems are typically formed by a myriad of many small interconnected de-vices. This underlying hardware infrastructure raises new chal-lenges in the way we administrate the software layer of these sys-tems. Indeed, the limited computing power and battery life of each node combined with the very distributed nature of these systems, greatly adds complexity to distributed software layer management. In this paper we propose a new middleware dedicated to CPS to enable the management of software deployment and the dynamic reconfiguration of these systems. Our middleware is inspired from the Component Based Systems and the model@runtime paradigm which has been adapted to the context of Cyber Physical Systems. We have conducted an initial evaluation on a typical Cyber Physical Systems hardware infrastructure which demonstrates the feasibility of providing a model@runtime middleware for these systems
