The ubiquity of 802.11 devices and networks enables anyone to track our every move with alarming ease. Each 802.11 device transmits a globally unique and persistent MAC address and thus is trivially identifiable. In response, recent research has proposed replacing such identifiers with pseudonyms (i.e., temporary, unlinkable names).

Fair Virtualization of 802.11 Networks
IEEE/ACM Transactions on Networking, 2015We consider virtualization of network capacity in 802.11 WLANs and mesh networks. We show that allocating total airtime slices to ISPs is analogous to allocating a fraction of available time-slots in TDMA. We establish that the max-min fair flow rate allocation within an ISP airtime slice can be characterized independently of the rate allocation policy

Measurements of In-Motion 802.11 Networking
Seventh IEEE Workshop on Mobile Computing Systems & Applications (WMCSA'06), 2006Wireless networking can support in-motion users by providing occasional opportunities to transmit and receive data. We measure the performance of UDP and TCP transfers between a car traveling at speeds from 5 mph to 75 mph and an 802.11b access point. We analyze the impact of bandwidth and delay limitations in the backhaul network on the feasibility of

IEEE 802.11 Latency Modeling with Non-IEEE 802.11 Interfering Source
2019IEEE 802.11 network deployments are ubiquitous and provide connectivity to millions of users. Interference that originates from other technologies, like simple Radio Frequency (RF) equipment, severely degrades the performance of those networks. To effectively manage wireless networks, the interference needs to be modeled and predicted.

Opportunistic Relays in 802.11 Networks
2014 IEEE 80th Vehicular Technology Conference (VTC2014-Fall), 2014We propose a new lightweight mechanism called Forwarding By Retransmission, that allows 802.11 stations to opportunistically relay overheard frames toward a destination. When a destination does not receive a frame, any other receiver that has better radio conditions than the source of the frame could participate in the retransmission process along with

GLOBECOM '05. IEEE Global Telecommunications Conference, 2005., 2005
In IEEE 802.11 WLANs, stations can operate at different data rates. For example, in 802.11b, wireless stations transmit at four date rates 11, 5.5, 2 and 1 Mbps. A station changes its modulation type and transmits at a lower rate when it faces signal fading and interference.

2010 International Conference on Machine Learning and Cybernetics, 2010
A Content Addressable Memory (CAM) is a storage array designed to quickly find the location of a particular stored value. By comparing the input with the data in memory, a CAM determines if an input value matches one or more values stored in the array. If a match exists, it is found in a single clock cycle. CAM is used buffer module in IEEE 802.11, the

The tremendous success of the Institute of Electronics and Electrical Engineering (IEEE) 802.11 wireless local area network (WLAN) standard led to severe competition. Due to Wi-Fi Alliance (WFA)'s marketing, 802.11 became a universal solution for wireless connectivity. However, still a WLAN depends on wired infrastructure that interconnects the central

Analysis of 802.11 Based Cognitive Networks and Cognitive Based 802.11 Networks
2010Cognitive radio has emerged as a new design paradigm for next generation wireless networks that aims to increase utilization of scarce radio spectrum. Intelligent algorithms are used to learn the surrounding environment, and the knowledge thus obtained is utilized by trans-receiver to achieve the best performance.
