Kom8ndor: An IEEE 802.11bn-Oriented Simulator for Wi-Fi 8 and Beyond
Francesc Wilhelmi, Sergio Barrachina-Muñoz, Boris Bellalta
The upcoming IEEE 802.11bn amendment marks a paradigm shift in Wi-Fi, which will pose ambitious performance targets under the paradigm of Ultra-High Reliability (UHR). To understan…
Decentralized Spatial Reuse Optimization in Wi-Fi: An Internal Regret Minimization Approach
Francesc Wilhelmi, Boris Bellalta, Miguel Casasnovas +2
Spatial Reuse (SR) is a cost-effective technique for improving spectral efficiency in dense IEEE 802.11 deployments by enabling simultaneous transmissions. However, the decentraliz…
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…
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…
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…
Learning-Based Channel Access in Wi-Fi: A Multi-Armed Bandit Approach
Miguel Casasnovas, Francesc Wilhelmi, Richard Combes +6
Due to its static protocol design, IEEE 802.11 (aka Wi-Fi) channel access lacks adaptability to address dynamic network conditions, resulting in inefficient spectrum utilization, u…
