A cross-layer mechanism for QoS improvements in VoIP over multi-rate WLAN networks

A cross-layer mechanism for QoS improvements in VoIP over multi-rate WLAN networks

In IEEE 802.11 WLANs, Link Adaptation mechanisms, which choose the transmission rate of each node, provoke unexpected and random variations on the effective channel capacity. When these changes are towards lower bitrates, inelastic flows, such as VoIP, can suffer from sudden congestion, which result...
