Roaming Free in the VR World with MP2
summary
A user-space centralized overlay called MP2 coordinates per-headset two Wi‑Fi interfaces via a centralized controller that collects RSSI and frame-size stats, models frame sizes with Gaussian mixtures to predict tail latency, and uses pruning and location partitioning to cut decision time to under one second for 48 users and 16 APs. MP2 uses multipass QUIC tunnels, warm-up probes and redundant transmission for seamless handover, and reports 35× tail-latency reduction, 1.56× bitrate, 1.86× QoE and up to 99.1% MOS gain in real tests and large emulation.
