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 ...
Design and implementation of a VIPSec based application
(2007)
Voice over IP (VoIP) is one of the most emerging technologies, while a respectable number of corresponding applications are being implemented or updated in daily basis. Although communications security is a constant ...
CDR-MAC: A protocol for full exploitation of directional antennas in ad hoc wireless networks
(2008)
In this paper, we propose a new Medium Access Control (MAC) protocol for full exploitation of directional antennas in wireless networks. The protocol introduces a circular directional transmission of the Request To Send ...
Community building over neighborhood Wireless Mesh Networks
(2008)
The fourth generation (4G) networks provide a converged environment for technology and service provision. The user-centric vision next-generation 4G is neighborhood Wireless Mesh Networks (WMNs). The vision for the formation ...
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 ...
Broadcast erasure channel with feedback-capacity and algorithms
(2009)
We consider the two-user broadcast erasure channel where feedback in the form of ack messages is fed back to the transmitter. We provide an upper bound to the capacity region of this system. We then present two algorithms ...
Dynamic resource allocation in CDMA systems with deterministic codes and multirate provisioning
(2006)
Next generation wireless CDMA systems will provide high and variable data rates by using multicode structures, controllable code spreading gains, and transmit power adaptation. We address the emerging resource allocation ...
Adaptive channel assignment in SDMA-based wireless LANs with transceiver resource limitations
(2006)
Beamforming with adaptive antenna arrays is the most promising means for increasing data rates of wireless systems, since it enables channel reuse by several users in a cell through space division multiple access (SDMA). ...
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 ...
