Research in IoT and WSN is focused on efficient data gathering and transmission. We develop sensors with embedded intelligence and original DSP capabilities to efficiently monitor different environments (partnering with Gefran, Nexperia, INDRA, etc. in several H2020 projects e.g. ENACT, I-MECH, Convergence). Additionally we have developed an evolving testbed for thorough testing of reliability, configurations, data transmission capacity, and energy consumption of our own and third-party IoT/WSNs.
