How Perception‑Aware Congestion Control Boosts Real‑Time Video QoE by Up to 32%

The paper introduces PACC, a perception‑aware congestion‑control algorithm that leverages a CNN‑based video‑quality sensor to adjust bitrate based on user‑perceived delay and quality trends, achieving 6.8%‑32.4% QoE improvements over existing model‑based, hybrid, and RL‑based schemes in diverse network conditions.
