6TiSCH Standardization Virtually Completed

Time Synchronized Channel Hopping (TSCH) is a Medium-Access Control (MAC) technique in which nodes synchronize, and a schedule orchestrates all communication in the network. Inria-EVA created the IETF 6TiSCH Working Group in 2013. The goal of 6TiSCH is to get the best of both world by combining TSCH (“industrial” performance) and the ease of use of IPv6 through the IETF upper stack (6LoWPAN, RPL, CoAP). Since the creation of 6TiSCH in October 2013, Thomas Watteyne co-chairs the working group, helps drive its technical developments, and coaches authors and authors technical documents. 6TiSCH also encompasses and important security aspect, where we look how to enable nodes to join a network efficiently, which includes mutual authentication between node and network. The 6TiSCH security solution if based on PSK, and relies on AES-128 CCM*.

421 people now follow the 6TiSCH activities through its mailing-list, with a healthy mix of industrial and academic contributors. In 2017, 6TiSCH has produced 2 RFCs, 6 working group document in the process of being published, and various individual submissions. The working group has met 3 times in person during 2017, tens of times through Webex. Inria-EVA co-organized a 6TiSCH interop event (attended by 15 entities) in July 2017. 6TiSCH is now supported by all major open-source implementations (OpenWSN , Contiki , RIOT, TinyOS), and several companies are building commercial product lines with it. 6TiSCH has been playing a real role of catalyst for the academic low-power wireless community, which has now mostly moved towards TSCH/6TiSCH.

Over 1,000 Sensors Deployed on 3 Continents

Inria-EVA uses SmartMesh IP as a low-power wireless building block for building end-to-end solutions. Deploying real networks allows Inria-EVA to do system-level cross-disciplinary research. Inria-EVA oversees over 1,000 sensors deployed on 3 continents:

• http://snowhow.io/. Monitoring the snowmelt process in the California Sierra Nevada. 945 sensors deployed in 21 networks. Collaboration with UC Berkeley Prof. Steven Glaser.

• http://www.savethepeaches.com/. Predicting frost events in peach orchards. 120 sensors deployed in Mendoza, Argentina. Collaboration with local agronomy/networking teams

• http://smartmarina.org/. Monitoring the occupancy and per-boat water/electricity consumption of the 3rd largest marina in Europe (Cap d'Agde, 4300 boats). Inria-EVA is working on turning this activity into a startup company.
