Comparison of modified dual queue and EDCA for VoIP over IEEE 802.11 WLAN
The popular IEEE 802.11 WLAN today does not provide any quality-of-service (QoS) because of its contention-based channel access nature of the medium access control (MAC). Therefore...

Adapting WLAN MAC parameters to enhance VoIP call capacity
This work describes a detailed simulation-based study of the performance of an IEEE 802.11e Medium Access Control (MAC) layer over an IEEE 802.11g Physical (PHY) layer. The study ...

Collision-aware design of rate adaptation for multi-rate 802.11 WLANs
One of the key challenges in designing a rate adaptation scheme for IEEE 802.11 wireless LANs (WLANs) is to differentiate bit errors from link-layer collisions. Many recent rate a...

An Autonomous Distributed Admission Control Scheme for IEEE 802.11 DCF
Admission control as a mechanism for providing QoS requires an accurate description of the requested flow as well as already admitted flows. Since 802.11 WLAN capacity is shared...
