Analysis of the Character Statics of Video Streaming on WLAN Networks

The bursty nature of video streaming applications is due to the frame-based structure of video and this has an important impact on the resource requirements of the WLAN, affecting its ability to provide Quality of Service (QoS) particularly under heavily loaded conditions. In this paper, the authors analyze the unique delay characteristic of video streaming applications in a WLAN environment. They show that the "Burstiness" of video is due to the frame-based nature of encoded video. They show how each video frame is transmitted as a burst of packets that is queued at the Access Point causing the delay to exhibit a sawtooth-like characteristic over time that is related to the frame rate and frame structure of the encoded video.
