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…
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…
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…
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…
NeSt-VR: An Adaptive Bitrate Algorithm for Wireless Virtual Reality Streaming
Miguel Casasnovas, Ferran Maura, Isjtar Vandebroeck +3
Interactive Virtual Reality (VR) streaming over wireless links requires both high frame rates and low motion-to-photon latency, requirements that are difficult to sustain under cha…
