Performance analysis of VR streaming under Wi-Fi 6
Lester He
Virtual reality (VR) gaming refers to running video games on a computer while using a VR headset as the display, which results in a more immersive experience than a monitor. Due to the immersive experience, the user base is expanding [1]. Now VR headset manufactures supports wireless streaming, which imposes a high requirement on both bandwidth (sending the images from the computer to the headset) and latency (sending the user input from the headset to the computer) of the network [2]. However, building a dedicated network for VR streaming [LH1.1]is expensive and may be wasteful. Therefore, to ensure a good quality of experience (QoE) [3] in a shared network, this project first assumes one user is streaming games to their VR headset, while other users are browsing the web or watching videos [4] using the same Wi-Fi 6 network [5], then analyzes how would other users’ traffic affect the VR gaming experience in terms of throughput available to the headset and latency experienced by the headset using ns-3.
