  • The Inria's Research Teams produce an annual Activity Report presenting their activities and their results of the year. These reports include the team members, the scientific program, the software developed by the team and the new results of the year. The report also describes the grants, contracts and the activities of dissemination and teaching. Finally, the report gives the list of publications of the year.

6TiSCH Benchmarking

Participants : Malisa Vucinic, Tengfei Chang, Yasuyuki Tanaka, Thomas Watteyne.

With the pure 6TiSCH standardizes coming to an end, the focus of the group is moving towards benchmarking how well it works. This has results in the following action. Although seemingly different, they all contribute to the overall goal of better understand (the performance of) 6TiSCH.

We have built and put online the OpenTestbed, a collection of 80 OpenMote B boards deployed in 20 “pods”. These allow us to test the performance of the OpenWSN firmware in a realistic setting. The testbed is depicted in Fig. 2. You can access its management interface at http://testbed.openwsn.org/.

A tool complementary to the testbed is the 6TiSCH simulator (https://bitbucket.org/6tisch/simulator) which Yatsuyiki Tanaka is leading. The simulator now represents exactly the behavior of the 6TiSCH protocol stack, and has been a catalyst for benchmarking activities around 6TiSCH.

Beyond Inria, the benchmarking activity around 6TiSCH is a hot topic, with projects such as the 6TiSCH Open Data Action (SODA, http://www.soda.ucg.ac.me/), the IoT Benchmarks Initiative (https://www.iotbench.ethz.ch/), and the Computer and Networking Experimental Research using Testbeds (CNERT) workshop at INFOCOM, all of which Inria-EVA is very involved in.
