Wireless local area networks (WLAN) are balanced to enable a variety of delay-sensitive multimedia applications, due to their flexible and low cost infrastructure. However, existing wireless networks provide only limited, time-varying quality of service (QoS) for delay-sensitive, bandwidth intense, and loss-tolerant multimedia applications. Fortunately, video transport can cope with a certain amount of packet losses depending on the sequence characteristics and error concealment strategies. Consequently, video transmission do not require complete insulation from packet losses, but rather that the application layer cooperate with the lower layers to select the optimal wireless transmission strategy that maximizes multimedia performance. This article focuses on a QoS cross-layer optimization based on both application layer and MAC layer features, in the transmission of H.264 video streams over WLAN.
