Network Coding in Large Scale IoT Networks

Participants : Cedric Adjih, Ichrak Amdouni, Hana Baccouch, Antonia Masucci.

We had designed a generic broadcast protocol, called DragonNet, based on network coding and designed for constrained networks such as wireless sensor networks and internet of things. It minimizes the assumptions made of the networks. A variant of this protocol was implemented and run on IoT-LAB: some results were initially presented at IRTF, and a live demo was presented in MASS in october 2014.

Information-Centric Networking in the Internet of Things

Participants : Emmanuel Baccelli, Oliver Hahm, Matthias Waehlisch, Thomas Schmidt, Christian Mehlis.

Within this activity, we explored the feasibility, advantages, and challenges of an ICN-based approach in the Internet of Things. We report on the first NDN experiments in a life-size IoT deployment, spread over tens of rooms on several floors of a building. Based on the insights gained with these experiments, we have analysed the shortcomings of CCN applied to IoT. Several interoperable CCN enhancements are then proposed and evaluated. We significantly decreased control traffic (i.e., interest messages) and leverage data path and caching to match IoT requirements in terms of energy and bandwidth constraints. Our optimizations increase content availability in case of IoT nodes with intermittent activity. Within this activity, we also provided the first experimental comparison of CCN with the common IoT standards 6LoWPAN/RPL/UDP.
