Automated Mobile Video Objective Testing System
Eric Petajan, Jonathan Lynam, Morey Antebi +5
Applying QoE analysis to optimize usage of cellular spectrum is of high interest to mobile network operators. A key challenge is to be able to perform QoE measurement across very d…
Prototyping QoE-Aware Rate Adaptation in Cellular Networks with Commercial Applications
Szilveszter Nádas, Lars Ernström, Dan Druta +4
Prior work has shown that QoE-aware resource sharing for real-time interactive video can support up to three times more simultaneous sessions at acceptable quality compared to rate…
Multi-Generator Continual Learning for Robust Delay Prediction in 6G
Xiaoyu Lan, Jalil Taghia, Hannes Larsson +1
In future 6G networks, dependable networks will enable telecommunication services such as remote control of robots or vehicles with strict requirements on end-to-end network perfor…
Towards a Robust Transport Network With Self-adaptive Network Digital Twin
Cláudio Modesto, João Borges, Cleverson Nahum +8
The ability of the Network digital twin (NDT) to remain aware of changes in its physical counterpart, known as the physical twin (PTwin), is a fundamental condition to enable timel…
Quantifying QoE-Aware Resource Sharing Potential Under Time-variant Spatial Complexity
Szilveszter Nádas, Lars Ernström, David Lindero +1
The spatial complexity of real-time interactive video varies significantly within a single session, not only across different content types. This renders static resource allocation…
Accelerating Ray Tracing-Based Wireless Channels Generation for Real-Time Network Digital Twins
Cláudio Modesto, Lucas Mozart, Pedro Batista +2
Ray tracing (RT) simulation is a widely used approach to enable modeling wireless channels in applications such as network digital twins. However, the computational cost to execute…
