Enabling Reliable Latency in Wi-Fi 8 Through Multi-AP Joint Scheduling
David Nunez;Pasquale Imputato;Stefano Avallone;Malcolm Smith;Boris Bellalta
IEEE Open Journal of the Communications Society
Year: 2025 | Early Access Article |
The rapid evolution of wireless communication systems, driven by increasing demands for high throughput, low latency, and reliable connectivity, presents significant challenges for traditional Wi-Fi networks. To address these limitations, the forthcoming IEEE 802.11bn amendment will likely introduce Multi-Access Point Coordination (MAPC) as a pivotal feature to enhance performance in dense network...Show More
IEEE 802.11bn Multi-AP Coordinated Spatial Reuse With Hierarchical Multi-Armed Bandits
Maksymilian Wojnar;Wojciech Ciezobka;Katarzyna Kosek-Szott;Krzysztof Rusek;Szymon Szott;David Nunez;Boris Bellalta
Coordination among multiple access points (APs) is integral to IEEE 802.11bn (Wi-Fi 8) for managing contention in dense networks. This letter explores the benefits of Coordinated Spatial Reuse (C-SR) and proposes the use of reinforcement learning to optimize C-SR group selection. We develop a hierarchical multi-armed bandit (MAB) framework that efficiently selects APs for simultaneous transmission...Show More
Spatial Reuse in IEEE 802.11bn Coordinated Multi-AP WLANs: A Throughput Analysis
David Nunez;Francesc Wilhelmi;Lorenzo Galati-Giordano;Giovanni Geraci;Boris Bellalta
2024 IEEE Conference on Standards for Communications and Networking (CSCN)
Year: 2024 | Conference Paper |
IEEE 802.11 networks continuously adapt to meet the stringent requirements of emerging applications like cloud gaming, eXtended Reality (XR), and video streaming services, which require high throughput, low latency, and high reliability. To address these challenges, Coordinated Spatial Reuse (CSR) can potentially contribute to optimizing spectrum resource utilization. This mechanism is expected to...Show More
Throughput Analysis of IEEE 802.11bn Coordinated Spatial Reuse
Francesc Wilhelmi;Lorenzo Galati-Giordano;Giovanni Geraci;Boris Bellalta;Gianluca Fontanesi;David Nuñez
2023 IEEE Conference on Standards for Communications and Networking (CSCN)
Year: 2023 | Conference Paper |
Cited by: Papers (2)
Multi-Access Point Coordination (MAPC) is becoming the cornerstone of the IEEE 802.11bn amendment, alias Wi-Fi 8. Among the MAPC features, Coordinated Spatial Reuse (C-SR) stands as one of the most appealing due to its capability to orchestrate simultaneous access point transmissions at a low implementation complexity. In this paper, we contribute to the understanding of C-SR by introducing an ana...Show More
Multi-AP Coordinated Spatial Reuse for Wi-Fi 8: Group Creation and Scheduling
2023 21st Mediterranean Communication and Computer Networking Conference (MedComNet)
Year: 2023 | Conference Paper |
Cited by: Papers (7)
Multi-Access Point Coordination (MAPC) will be a key feature in next generation Wi-Fi 8 networks. MAPC aims to improve the overall network performance by allowing Access Points (APs) to share time, frequency and/or spatial resources in a coordinated way, thus alleviating inter-AP contention and enabling new multi-AP channel access strategies. This paper introduces a framework to support periodic M...Show More
TXOP sharing with Coordinated Spatial Reuse in Multi-AP Cooperative IEEE 802.11be WLANs
2022 IEEE 19th Annual Consumer Communications & Networking Conference (CCNC)
Year: 2022 | Conference Paper |
Cited by: Papers (22)
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 mind, transmit opportunity (TXOP) sharing between coordinated access points (APs) may contribute to alleviating inter-AP contention, hence increasing the overall network throughput. This paper evaluates two coordinated TX...Show More
