Performance of video over an IEEE 802.11a wireless LAN

There are obvious differences between video and data frame transmission in WLAN, for the video streams need to provide people with consequent and distinct scene. Thus we should concern with the transmission delay and throughput for the video frame. In transmission, the long video frame would be segmented, and then fill into the SDU. Different frame rate and size lead to different MAC layer transmission performance such as delay and throughput. In this paper, a precise scheme is proposed to analysis the video transmission performance in IEEE 802.11a WLAN. With different frame rate, the relationship between frame size and video numbers has been conducted, and video throughput has been preciously calculated.
