Learning uplinks and downlinks transmissions in RF-charging IoT networks [PDF]
Scientific ReportsThis paper considers uplink and downlink transmissions in a network with radio frequency-powered Internet of Things sensing devices. Unlike prior works, for uplinks, these devices use framed slotted Aloha for channel access.

An Uplink Random Access Scheme Based on ALOHA System Assisted by Gain Division Multiple Access
IEEE Access, 2023 Gain division multiple access (GDMA) is a non-orthogonal multiple access (NOMA) technique for uplink communications. In GDMA, the receiver employs both the magnitudes and phases of channel gains associated to the users to separate users.

Improving LoRaWAN Performance Using Reservation ALOHA [PDF]
Journal of Information Technology Management, 2020 LoRaWAN is one of the new and updated standards for IoT applications. However, the expected high density of peripheral devices for each gateway, and the absence of an operative synchronization mechanism between the gateway and peripherals, all of which ...

Shifted Coded Slotted ALOHA [PDF]
2018 International Symposium on Information Theory and Its Applications (ISITA), 2018 The random access scheme is a fundamental scenario in which users transmit through a shared channel and cannot coordinate each other. In recent years, successive interference cancellation (SIC) was introduced into the random access scheme. It is possible to decode transmitted packets using collided packets by the SIC. The coded slotted ALOHA (CSA) is a

Collision-aware distributed detection with population-splitting algorithms
EURASIP Journal on Wireless Communications and Networking, 2021 We consider the design of distributed detection algorithms for single-hop, single-channel wireless sensor networks in which sensor nodes send their local decisions to a fusion center (FC) by using a random access protocol.
