The main objective of this research is to develop a contention-based medium access control (MAC) scheme for the IEEE 802.11 wireless local area network (WLAN), so that quality of service (QoS) can be guaranteed, i.e., throughput and delay requirements for real-time traffics are satisfied. Meanwhile, best-effort data traffics are able to access wireless medium efficiently and fairly.

520 $a The main objective of this research is to develop a contention-based medium access control (MAC) scheme for the IEEE 802.11 wireless local area network (WLAN), so that quality of service (QoS) can be guaranteed, i.e., throughput and delay requirements for real-time traffics are satisfied. Meanwhile, best-effort data traffics are able to access wireless medium efficiently and fairly.
520 $a Throughout this research, we undertake this challenging task in four steps. Firstly, we develop a two-level protection and guarantee scheme to provide QoS guarantees for constant bit rate (CBR) real-time traffics in infrastructure WLANs. Then, we propose a fully distributed local data control and admission control scheme to provide QoS guarantees for CBR real-time traffics in ad hoc WLANs. Next, we study a series of bandwidth sharing schemes to efficiently utilize resource in WLANs. Finally, we further improve our admission control and best-effort control schemes to provide QoS guarantees for variable bit rate (VBR) real-time traffics in WLANs. Analysis and extensive simulations demonstrate that our MAC schemes are effective and efficient in terms of providing QoS guarantees for real-time traffics in the IEEE 802.11 WLAN, as well as the utilization of the channel capacity.
