Distributed prioritized channel access mechanisms have been adopted by the IEEE 802.11
e enhanced distributed channel access (EDCA) and the Multiband OFDM Alliance …

In this paper, we present a model to analyze the throughput and delay performance of the
EDCA mechanism under non saturation conditions. The main strength of our model is that it …

In this paper, we propose an analytical model for the performance evaluation of IEEE 802.11
e enhanced distributed channel access (EDCA). Different from most previous analytical …

In this paper, we propose an analytical model to evaluate the hidden station effect on both
non-saturation and saturation performance of the IEEE 802.11 Distributed Coordination …

In this paper, we present an analytical model to evaluate the hidden station effect on the
access delay of the IEEE 802.11 distributed coordination function (DCF) in both non …

To overcome the lack of strict QoS guarantees in existing hotspots, in this paper we present
a system for realtime traffic support in 802.11 networks that works in either infrastructure or …

Patients with severe physical disorders but who are cognitively intact find it difficult to
communicate with the outside world. Researches on the brain-computer interface (BCI) are …

We examine two approximative models for the behavior of an IEEE 802.11 WLAN under
Poisson MAC-level arrivals. Both models extend, in a simple manner, the analysis for …

How to improve the radio resource utilization and provide better quality-of-service (QoS) is
an everlasting challenge to the designers of wireless networks. As an indispensable …

This paper proposes a medium access control (MAC) protocol that provides quality of
service (QoS) in voice over IP (VoIP) over Wireless Local Area Networks (WLANs). Our …
