Evaluating Wi-Fi Performance for VR Streaming: A Study on Realistic HEVC Video Traffic
Ferran Maura, Francesc Wilhelmi, Boris Bellalta
Cloud-based Virtual Reality (VR) streaming presents significant challenges for 802.11 networks due to its high throughput and low latency requirements. When multiple VR users share…
Performance Evaluation of Multi-Armed Bandit Algorithms for Wi-Fi Channel Access
Miguel Casasnovas, Francesc Wilhelmi, Richard Combes +6
The adoption of dynamic, self-learning solutions for real-time wireless network optimization has recently gained significant attention due to the limited adaptability of existing p…
Deep Reinforcement Learning-Based Scheduling for Wi-Fi Multi-Access Point Coordination
David Nunez, Francesc Wilhelmi, Maksymilian Wojnar +3
Multi-access point coordination (MAPC) is a key feature of IEEE 802.11bn, with a potential impact on future Wi-Fi networks. MAPC enables joint scheduling decisions across multiple…
Improving Wi-Fi 8 Latency with Coordinated Spatial Reuse
David Nunez, Francesc Wilhelmi, Lorenzo Galati-Giordano +2
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 re…
Wi-Fi: Twenty-Five Years and Counting
Giovanni Geraci, Francesca Meneghello, Francesc Wilhelmi +7
Today, Wi-Fi is over 25 years old. Yet, despite sharing the same branding name, today's Wi-Fi boasts entirely new capabilities that were not even on the roadmap 25 years ago. This…
Can cloud-based VR streaming handle Wi-Fi OBSS contention?
Miguel Casasnovas, Marc Carrascosa-Zamacois, Boris Bellalta
This paper experimentally analyzes the negative impact of contention caused by neighboring Wi-Fi networks operating on overlapping channels on Virtual Reality (VR) streaming over W…
