Redundancy Transmission in UAV-Aided LoRa Networks Featuring Wake-Up Radios
<|reference_start|>Redundancy Transmission in UAV-Aided LoRa Networks Featuring Wake-Up Radios: We consider a LoRa sensor network featuring a UAV-mounted gateway for collecting sensor data (messages). Wake-up radios (WuR) are employed to inform the sensors of the UAV's arrival. Building on an existing random access scheme for such setups, we propose and evaluate two redundancy transmission protocols for enhancing the reliability of the data transfer. One protocol employs fountain-coded transmissions, whereas the other performs message replication. Our results illustrate how redundancy transmission can be beneficial under the time constraints imposed by the UAV's limited hovering duration, and how node density, hovering time, and sensor energy budget impact the performance of the schemes.<|reference_end|>
