Joint beamforming and channel selection for multicast IEEE 802.11n WLANs
(2008)
Multicast transmission over WLANs is becoming a popular application. IEEE 802.11n technology is developed due to the ever increasing demand for higher data rate and Quality of Service (QoS). However, there is an unmanaged ...
Low-complexity beamforming techniques for IEEE 802.11n WLANs
(2009)
The impetus of the present study is to describe a downlink beamforming method that increase spectrum efficiency and significantly reduces implementation complexity and power consumption compare to beamforming technique at ...
Interference mitigation in co-working IEEE 802.11n WLANs
(2009)
In a densely deployed Wireless Local Area Network (WLAN) environment, Access Points (APs) could be so close to cause significant channel interference. In the next generation IEEE 802.11n WLANs, inter-cell interference ...
FIJI: Fighting implicit jamming in 802.11 WLANs
(2009)
The IEEE 802.11 protocol inherently provides the same long-term throughput to all the clients associated with a given access point (AP). In this paper, we first identify a clever, low-power jamming attack that can take ...
LAC: Load-aware channel selection in 802.11 WLANs
(2008)
Dense deployments of hybrid WLANs result in high levels of interference and low end-user throughput. Many frequency allocation mechanisms for WLANs have been proposed by a large body of previous studies. However, none of ...
A demonstration of video over a user centric prioritization scheme for wireless LANs
(2008)
Due to the unreliable nature of the wireless medium, provisioning of the Quality of Service (QoS) in wireless LANs is by far more complicated than in wired networks. In this demo we show the efficiency of a new QoS support ...
Multicast transmission over IEEE 802.11n WLAN
(2008)
With the advent of low-cost WLAN devices, the delivery of multimedia content is highly desirable. Such applications require high throughput and near-real time for quality viewing. The use of next-generation WLAN 802.11n ...
New prioritization schemes for QoS provisioning in 802.11 wireless networks
(2008)
Due to the unreliable nature of the wireless medium, provisioning of Quality of Service (QoS) in wireless LANs is far more complicated than in wired networks. In order to address this challenge, IEEE 802.11e defines a ...
Joint multicast beamforming and admission control
(2007)
Wireless multicasting is quickly emerging as an important enabling technology for mass content distribution to mobile hand-held devices. With channel state information at the transmitter, it is possible to tailor transmissions ...
