Cover Story: In the last decade, Wake-up Radio technology has gained more and more importance for IoT applications. This technology is based on an ultra-low-power, always-listening radio receiver that prevents the main IoT transceiver to continuously listen to the channel, lowering its power consumption. On the other hand, LoRa is one of the emerging long-range standards that facilitate the environmental monitoring of wide areas, but generally suffer from high latency in downlink. This paper proposes an original combination of Lora technology and Wake-up radio to improve the performance (latency and energy) of the LoRaWAN downlink transmission. It is also shown that this combination is particularly suitable to nodes that have the capability to harvest surrounding energy. This research is mainly funded by French ANR and takes place in the collaborative project “Wake-Up”. View this paper
