Synchronous transmissions

Over the years, the Computer Engineering Group (TEC) at ETH Zurich has conducted various research projects regarding synchronous transmission of packets by flooding of a wireless sensor network (WSN). This page serves as an overview over the different resources which have evolved during this pursuit.

If you are interested in synchronous transmissions on GFSK as well as LoRa modulations, we have built a low-layer support library called Flora which contains many helper functions for higher-layer protocols. Flora is publicly available on GitLab and is used for some of the projects mentioned below (LWB, eLWB and STeC).
