A study of QoS feedback schemes on WiFi multicast for media streaming services
Nowadays multimedia streaming is running on mobile devices under WiFi networks. To send the same media stream to multiple receivers, multicast is usually considered for efficient data transmission. Since multicast frames won't be acknowledged, it is difficult to evaluate the QoS of data delivery over WiFi. In this work, we proposed a so called Statistic Collection multicast scheme based on X-beacon mechanism and corresponding MAC management messages for WiFi multicast. Our work features the following characteristics: (1) implements acknowledgement for multicast, (2) improves awareness on WiFi multicast, (3) measures transmission power and performs power-adjustment, and (4) extends the coverage for all receivers.
