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…
Network-Coded Cooperative LoRa Network with D2D Communication
L. H. O. Alves, J. L. Rebelatto, R. D. Souza +1
We evaluate the outage probability and the energy efficiency (EE) of a LoRa network when the end-devices (EDs) are capable of exchanging messages with a device-to-device (D2D) tech…
Massive Wireless Energy Transfer with Multiple Power Beacons for very large Internet of Things
Osmel Martínez Rosabal, Onel L. Alcaraz López, Hirley Alves +2
The Internet of Things (IoT) comprises an increasing number of low-power and low-cost devices that autonomously interact with the surrounding environment. As a consequence of their…
