Environment monitoring, home automation, or tracking wild animals, the applications for communicating sensors abound, and are fast moving into our daily lives. Tomorrow, they will be replacing cables in cars. This explains why the French National Research Agency (Agence Nationale de la Recherche, ANR) launched the three-year Telecommunications program to test very large open wireless sensor networks, in 2008. As a result, the SensLab platform has been deployed at four INRIA sites (Lille, Grenoble, Rennes and Strasbourg). The 1,024 node platform will be studying full-size networks. The program brings together three INRIA teams (D-Net, Pops and Asap) and their partners, Thales, and Strasbourg and Pierre and Marie Curie Paris VI universities.
Although simulations can be used to test networks relying on a thousand or more sensors, they cannot study every configuration. It has been proven that the same protocol tested on different simulators does not provide the same result. So, full-size tests have to be set up on an open pre-equipped platform such as SensLab. All a researcher has to do is connect to the platform site, download the test code and configure the test.
Two hundred and fifty-six sensors will be installed at each of the four sites. In Lille for instance, the sensors will be deployed as a grid in a showroom at EuroTechnologies. Thirty-two sensors will be mobile while the others will be set up on two superposed Plexiglas boards hanging three meters above the floor. Its inauguration has been scheduled for February. The site at the Grenoble INRIA Center has been operational since last November 24th.
