Opportunistic Access with Random Subchannel Backoff (OARSB) for OFDMA Uplink
Abstract— A distributed medium access control (MAC) algorithm for uplink OFDMA networks under the IEEE 802.16 framework is proposed and analyzed in this work. We present a simple...

QoE estimation from MAC-level QoS in audio-video transmission with IEEE 802.11e EDCA
— This paper estimates Quality of Experience (QoE), i.e., user–level QoS from MAC–level QoS for audio–video transmission over an IEEE 802.11e EDCA wireless LAN. The MAC– ...
