ABSTRACT
With the increasing demands on real-time services in a Wireless LAN system, it is critical that the controls provided in WLAN are sufficient to ensure the required QoS. In this study, besides the EDCF and HCF control algorithms defined in the IEEE 802.11e, an enhanced timer-based control algorithm is proposed to effectively manage the delay budget. A simulation platform is developed to quantify the QoS performance and provides a frame work for developing new QoS control algorithms. The comparison between the proposed control algorithms and the traditional EDCF and HCF controls are also evaluated.

Virtual reservation scheme for supporting CBR multimedia services with strict QoS performance over WLAN and wireless mesh
Carrier sense multiple access and its variants have been widely used in mobile ad hoc networks. However, most existing access mechanisms cannot guarantee quality of service for real-time traffic. In this paper, we present a novel approach to guarantee ...
An efficient scheduling and admission control algorithm for IEEE 802.11e WLAN
ICUIMC '08: Proceedings of the 2nd international conference on Ubiquitous information management and communicationIEEE 802.11e is being proposed to improve QoS (Quality of Service) by IEEE 802.11 working group. HCCA (HCF Controlled Channel Access), a centralized polling based mechanism of IEEE 802.11e, needs a scheduling algorithm that decides on how the available ...
