The 2nd French Pilot (second phase of SCENE Pilots) was conducted on the 17th of December 2020 in Rennes, France. Due to the COVID-19 restrictions, the tests were conducted from a car instead of a bus, and the partners were following and supporting the tests from a live Microsoft Teams’ session, thus assuring the remote presence of AlmavivA (Italy), CEA (France) and VisionWare (Portugal). The French use case is about Air Quality monitoring. But for this second phase, we changed the air quality sensor, and extended the testing route by adding two municipalities around Rennes city. The Air Quality sensor unit was the Nova Sensor SDS011 laser PM2.5/PM10 associated with the GPS Receiver BS-708. Based on the same laser scattering principle than in the previous pilot, it detected the presence of particle concentration in the air between 0.3 to 10μm. Two Intelligent Gateways were used during the Pilot. One was mounted inside the car together with the Air Quality sensor, and the other one was installed in the JCP-Connect premises for mesh networking tests related to Content Delivery. All the working Intelligent Gateways processed the data received from the sensor and generated messages for the SCENE Service Platform. The tests particularly evaluated the data buffering feature, measured by the data loss KPI. Another series of tests were conducted on the Content Delivery modules implemented in the Intelligent Gateway (Content Prefetching, HTTPS based Content Caching). These modules were tested using a “user mobility scenario”. During the tests, different networks (i.e., 4G, WIFI) and different implementations (Mesh Networking and OpenVPN for Remote IGW Access) were also used. Despite the encountered difficulties regarding COVID-19 pandemic, and thanks to the support of all partners, a second version of SCENE Platform has been successfully tested and the 2nd phase pilot’s goals were achieved.
