Virtualization of wireless LAN infrastructures

Proceedings of the 6th IEEE International Conference on Intelligent Data Acquisition and Advanced Computing Systems, 2011
In wired Ethernet networks (IEEE 802.3), physical network interfaces can be connected to different network segments or shared among multiple virtual machines. In wireless LAN (IEEE 802.11) sharing wireless network interfaces is recognized to be a difficult task. However, virtualization can solve this problem.

A high-speed wireless LAN

IEEE Micro, 1997
WLAN systems face technical problems similar to those encountered in outdoor wide-area radio-based systems, including the limited available bandwidth and fading noise due to multipath interference and blockage. The goal in WLAN system design is to transmit at the maximum information rate with an acceptable probability of error and minimum equipment ...

Wireless LANs - Present and Future

BT Technology Journal, 2003
Wireless LAN technology has grown rapidly in importance over the last two years, because it fills a real user need at a cost the user can afford. This paper firstly provides a brief description of the main technology used for wireless LANs today.

Wireless LANs and 'neighborhood capture'

The 13th IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2003
A new capture effect, 'neighborhood capture', is described, which arises when Ethernet-type protocols are employed in multiple-cell wireless local area networks (WLANs) that re-use RF channels. Given the small number of channels available, cochannel cells cannot all transmit simultaneously without causing interference on one another.

Wireless lans with smart antennas [PDF]

, 2005
ABSTRACT Smart antenna systems not only enable users to have high quality links but also increase network throughput by allowing spatial reuse of wireless channels by the use of directional transmission. However performance of smart antenna systems is limited because of the increased hidden terminal problem and deafness of nodes.

A scalable wireless virtual LAN

Proceedings of the 2nd annual international conference on Mobile computing and networking, 1996
This paper presents a Wireless Virtual Local Area Network (WVLAN) to support mobility in IP‐over‐ATM local area networks. Mobility is handled by a joint ATM‐layer handoff for connection rerouting and MAC‐layer handoff for location tracking, such that the effects of mobility are localized and transparent to the higher‐layer protocols.

Standardization efforts for wireless LANs

IEEE Network, 1991
The Digital European Cordless Telecommunications (DECT) draft standard, which is the only wireless local area network (LAN) standard close to the 1-Mb/s data rate is briefly described. Active standards groups and their activities are reviewed. The work of the IEEE working groups for wireless LANs is examined. >

Enabling Wireless LAN Troubleshooting

2015
Particular WLAN pathologies experienced in realistic scenarios are hard to detect, due to the complex nature of the wireless medium. Prior work has employed sophisticated equipment, driver modifications, or even application-layer techniques, towards diagnosing such pathologies.

Benchmarking Wireless LAN Location Systems Wireless LAN Location Systems

Second IEEE International Workshop on Mobile Commerce and Services, 2006
Wireless LANs not only provide an affective means of communication, but also allow to extract information about the location of mobile stations. Numerous wireless LAN location systems have been proposed in the past, yet it is difficult to compare the performance of different systems, since the conditions under which these systems are evaluated differ ...

On the Stable Throughput in Wireless LANs

2015
The throughput stability is concerned with how much traffic load can be sustained in a network, and has been a research hotspot. Recent studies on the stability in 802.11 networks have arrived at contradictory conclusions. This paper delves into the reasons behind these contradictions.
