IEEE Synchronized CSMA Contention: Model, Implementation, and Evaluation
A class of carrier sense multiple access (CSMA) protocols used in a broad range of wireless applications uses synchronized contention where nodes periodically contend at intervals of fixed duration. While several models exist for asynchronous CSMA contention used in protocols like IEEE 802.11 MAC, no model exists for synchronized CSMA contention that also incorporates realistic factors like clock drifts. In this paper, we introduce a model that quantifies the interplay of clock drifts with contention windo...
InfoWorld Cisco weighs in for multi-gigabit addition to Wi-Fi
A high-frequency supplement to Wi-Fi that's several times faster than most of what's available now appears headed for enterprises through a partnership between Cisco Systems and a specialist in the technology.
InfoWorld Wireless charging from 30 feet away -- does startup have a game changer?
A startup Tuesday unveiled technology it claims can can simultaneously charge multiple different devices in a house, even through walls and around corners, by using the same radio spectrum as other wireless standards, such as Wi-Fi and Bluetooth. "You don't have to put that device in every room. You just put it into one room in your house and it will power all your devices," said Hatem Zeine, founder of Ossia, developer of the technology. "It's like your Wi-Fi signal. If you can get a Wi-Fi signal, you'll ...
InfoWorld Wireless USB to get high-speed jolt from WiGig
The WiGig high-speed wireless standard will power a new wireless version of USB through a deal between the Wi-Fi Alliance and the USB Implementers Forum. The Wi-Fi Alliance has transferred a specification for the WiGig high-frequency technology to the USB-IF as part of a broader effort to work with third parties to make WiGig useful.
InfoWorld Wi-Fi's fast 802.11ac standard may pay off big in mobile
The emerging IEEE 802.11ac wireless LAN standard will be able to deliver faster connections wherever it's used, but the biggest benefit may come at public hotspots -- eventually.
