Within the LPWAN framework, the LoRa modulation adopted by LoRaWAN technology has garnered significant interest as a connectivity solution for IoT applications due to its ability t…
Reinforcenment Learning-Aided NOMA Random Access: An AoI-Based Timeliness Perspective
Felippe Moraes Pereira, Jamil de Araujo Farhat, João Luiz Rebelatto +2
In this paper, we investigate the age-of-information (AoI) of a power domain non-orthogonal multiple access (NOMA) network, where multiple internet-of-things (IoT) devices transmit…
Probabilistic Allocation of Payload Code Rate and Header Copies in LR-FHSS Networks
Jamil de Araujo Farhat, Jean Michel de Souza Sant'Ana, João Luiz Rebelatto +3
We evaluate the performance of the LoRaWAN Long-Range Frequency Hopping Spread Spectrum (LR-FHSS) technique using a device-level probabilistic strategy for code rate and header rep…
