Video Stream Groupcast Optimization in WLAN
Zhengyong Feng, Guangjun Wen, Chunlei Yin, Hongsheng Liu · 2010
With the presentation of more reliable groupcast proposal for IEEE802.11 WLAN, the QoS of video transmission based on groupcast (multicast / broadcast) is improved. To adapt the network load and bandwidth dynamic change in WLAN environment, we design a flexible optimization mechanism that integrates video steam priority character with more reliable groupcast technology. Simulation validates it is efficient especially in unsatisfied bandwidth support condition.
