Over the past few years, wireless networking technologies have made vast forays into our
daily lives. Today, one can find 802.11 hardware and other personal wireless technology …

The proliferation of hotspots based on IEEE 802.11 wireless LANs brings the promise of
seamless Internet access from a large number of public locations. However, as the number …

IEEE 802.11 works properly only if the stations respect the MAC protocol. We show in this
paper that a greedy user can substantially increase his share of bandwidth, at the expense …

The popularity of IEEE 802.11 WLANs has led to dense deployments in urban areas. High
density leads to sub-optimal performance unless the interfering networks learn how to …

Wireless access networks scale by replicating base stations geographically and then
allowing mobile clients to seamlessly" hand off" from one station to the next as they traverse …

802.11 a, b, and g standards were designed for deployment in cooperative environments,
and hence do not include mechanisms to protect from jamming attacks. In this paper, we …

We have made detailed measurements, on the impact of modern Wireless LAN technologies
on the IEEE 802.15. 4 in the 2.4 GHz ISM band. We have specifically focused on IEEE …

The combination of unlicensed spectrum, cheap wireless interfaces and the inherent
convenience of untethered computing have made 802.11 based networks ubiquitous in the …

We analyze wireless measurements taken during the SIGCOMM 2004 conference to
understand how well 802.11 operates in real deployments. We find that the overhead of …

We study the impact on 802.11 networks of RF interference from devices such as Zigbee
and cordless phones that increasingly crowd the 2.4 GHz ISM band, and from devices such …
