To provide efficient wireless video streaming service, the rate adaptation scheme should be applied at the low layer and the quality adaptation scheme should be considered at the high layer. To meet this requirement of wireless video streaming, we propose a new cross-layer design for video streaming over wireless networks. This design includes the rate(More)
Existing streaming protocols have no consideration for the characteristics of streaming applications because they only consider the network stability. In this paper, in order to overcome limitations of the previous schemes for video streaming, we propose a new video streaming mechanism called ”MaVIS (Media-aware Video Streaming)”. The MaVIS takes more(More)
IEEE 802.11 WLANs provide multiple transmission rates to improve the system throughput by adapting the transmission rate to the current wireless channel conditions. Many rate adaptation schemes have been proposed because IEEE 802.11 WLAN standard does not contain any specifications for the rate adaptation scheme. In this paper, in order to overcome(More)
The rate adaptation scheme refers to the adaptation of the client's transmission mode with the goal of selecting the optimal transmission mode that will give the maximum performance for the given wireless channel conditions. However, the rate adaptation scheme introduces a performance anomaly problem which degrades the channel utilization of the WLAN(More)
