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…
Performance Analysis of 6TiSCH Networks Using Discrete Events Simulator
Guilherme de Santi Peron, Marcos Eduardo Pivaro Monteiro, João Luís Verdegay de Barros +2
The Internet of Things (IoT) empowers small devices to sense, react, and communicate, with applications ranging from smart ordinary household objects to complex industrial processe…
Decentralized RL-Based Data Transmission Scheme for Energy Efficient Harvesting
Rafaela Scaciota, Glauber Brante, Richard Souza +4
The evolving landscape of the Internet of Things (IoT) has given rise to a pressing need for an efficient communication scheme. As the IoT user ecosystem continues to expand, tradi…
Coordinated Pilot Transmissions for Detecting the Signal Sparsity Level in a Massive IoT Network under Rayleigh Fading
Onel L. A. López, Glauber Brante, Richard D. Souza +2
Grant-free protocols exploiting compressed sensing (CS) multi-user detection (MUD) are appealing for solving the random access problem in massive machine-type communications (mMTC)…
Exploring the Non-Overlapping Visibility Regions in XL-MIMO Random Access Protocol
José Carlos Marinello Filho, Glauber Brante, Richard Demo Souza +1
The recent extra-large scale massive multiple-input multiple-output (XL-MIMO) systems are seen as a promising technology for providing very high data rates in increased user-densit…
Two-Stage Channel Estimation for Hybrid RIS Assisted MIMO Systems
Rafaela Schroeder, Jiguang He, Glauber Brante +1
Reconfigurable intelligent surfaces (RISs) have been proposed as a key enabler to improve the coverage of the signals and mitigate the frequent blockages in millimeter wave (mmWave…
Maximum Secrecy Throughput of MIMOME FSO Communications with Outage Constraints
Marcos Eduardo Pivaro Monteiro, João Luiz Rebelatto, Glauber Brante +1
In this work, we consider a scenario where two multiple-aperture legitimate nodes (Alice and Bob) communicate by means of Free-Space Optical (FSO) communication in the presence of…
On the Secure Energy Efficiency of TAS/MRC with Relaying and Jamming Strategies (Extended Version)
Jamil Farhat, Glauber Brante, Richard Demo Souza
In this paper we investigate the secure energy efficiency (SEE) in a cooperative scenario where all nodes are equipped with multiple antennas. Moreover, we employ secrecy rate and…
Employing Antenna Selection to Improve Energy-Efficiency in Massive MIMO Systems
Masoud Arash, Ehsan Yazdian, Mohammad sadegh Fazel +2
Massive MIMO systems promise high data rates by employing large number of antennas, which also increases the power usage of the system as a consequence. This creates an optimizatio…
On the Performance of Secure Full-Duplex Relaying under Composite Fading Channels
Hirley Alves, Glauber Brante, Richard D. Souza +2
We assume a full-duplex (FD) cooperative network subject to hostile attacks and undergoing composite fading channels. We focus on two scenarios: \textit{a)} the transmitter has ful…
