Is Collision-Free Backoff Worth It in Wi-Fi?
Mohammad Yousefi, Francesc Wilhelmi, Boris Bellalta
The Distributed Coordination Function (DCF)---the underlying channel access protocol in Wi-Fi, based on Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) and Binary…
On the Allocation of Transmit Power for Coordinated Spatial Reuse in IEEE 802.11bn Multi-Access Point Coordination
Francesc Wilhelmi, Boris Bellalta
IEEE 802.11bn (11bn) introduces Coordinated Spatial Reuse (Co-SR), a Multi-Access Point Coordination (MAPC) scheme where two APs coordinate to control the transmit power for a simu…
Can Machine Learning Break Wi-Fi Privacy? A Study on MAC Address Randomization
Marta Puig, Costas Michaelides, Lucia Pintor +2
Medium Access Control (MAC) address randomization has been widely adopted during the IEEE 802.11 network discovery phase as a countermeasure against passive tracking. This paper ex…
BRAVR: An AP-Assisted Online DRL Mechanism for Interactive VR Bitrate Adaptation over Wi-Fi
Miguel Casasnovas, Francesc Wilhelmi, Boris Bellalta
Interactive virtual reality (VR) streaming over Wi-Fi requires stringent latency and reliability guarantees, which become increasingly difficult to achieve under dynamic channel co…
A Tutorial on IEEE 802.11bn Multi-AP Coordination for Wi-Fi 8: From Standardization to Performance Evaluation
Francesc Wilhelmi, Boris Bellalta, Giovanni Geraci +5
The IEEE 802.11bn amendment defines significant modifications to the standard by establishing Ultra High Reliability (UHR) targets in Wireless Local Area Networks (WLANs). This is…
"It's Your Turn": A Novel Channel Contention Mechanism for Improving Wi-Fi's Reliability
Francesc Wilhelmi, Lorenzo Galati-Giordano, Gianluca Fontanesi
The next generation of Wi-Fi, i.e., the IEEE 802.11bn (aka Wi-Fi 8), is not only expected to increase its performance and provide extended capabilities but also aims to offer a rel…
Distributed Learning for Wi-Fi AP Load Prediction
Dariush Salami, Francesc Wilhelmi, Lorenzo Galati-Giordano +1
The increasing cloudification and softwarization of networks foster the interplay among multiple independently managed deployments. An appealing reason for such an interplay lies i…
ConPA: A Contention-free Mechanism with Power Adaptation for Beyond Listen-Before-Talk
Francesc Wilhelmi, Paolo Baracca, Gianluca Fontanesi +1
In view of the need to find novel means to utilize the unlicensed spectrum to meet the rising latency and reliability requirements of new applications, we propose a novel mechanism…
AI/ML-based Load Prediction in IEEE 802.11 Enterprise Networks
Francesc Wilhelmi, Dariush Salami, Gianluca Fontanesi +2
Enterprise Wi-Fi networks can greatly benefit from Artificial Intelligence and Machine Learning (AI/ML) thanks to their well-developed management and operation capabilities. At the…
TXOP sharing with Coordinated Spatial Reuse in Multi-AP Cooperative IEEE 802.11be WLANs
David Nunez, Francesc Wilhelmi, Stefano Avallone +2
IEEE 802.11be networks (aka Wi-Fi 7) will have to cope with new bandwidth-hungry and low-latency services such as eXtended Reality and multi-party cloud gaming. With this goal in m…
