Rate Adaptation in Unlicensed Bands under Smart Jamming Attacks
"... Abstract—Wireless communication protocols for unlicensed frequency bands support rate adaptation algorithms (RAAs) to cope with time-varying channel conditions. RAAs are not designed to operate against adversarial behavior, however. In this work, we analyze the vulnerabilities of two state-of-the-ar ..."

Local Optimum Based Power Allocation Approach for Spectrum Sharing in Unlicensed Bands
"... Abstract. We present a novel local optimum based power allocation approach for spectrum sharing in unlicensed frequency bands. The proposed technique is based on the idea of dividing the network in a number of smaller sub-networks or clusters. Sum capacity of each cluster is maximized subject to co ..."

A Spectrum Etiquette Protocol for Efficient Coordination of Radio Devices in Unlicensed Bands
"... Abstract — This paper presents a spectrum etiquette protocol for efficient coordination of radio communication devices in unlicensed (e.g. 2.4 GHz ISM and 5 GHz U-NII) frequency bands. The proposed etiquette method enables spectrum coordination between multiple wireless devices using different radio ..."

Indoor and Outdoor Femto Cells A Framework for Femtocells to Access Both Licensed and Unlicensed Bands
"... Abstract—Cellular operators have been offloading data traffic from their licensed bands to unlicensed bands through a large number of WiFi hotspots over the past years. Although this approach improves the cellular network capacity to some extent, it falls short of getting significant throughput gain ..."

ABSTRACT OF THE THESIS Multi-Radio Interference Diagnosis in Unlicensed Bands using Passive Monitoring
, 2011
"... The increasing density and data rate of unlicensed band wireless devices has led to significant inter- and intra-radio interference problems. Multiple competing standards such as the IEEE 802.11b/g, Bluetooth and ZigBee, all of which operate in the 2.4 GHz ISM band, can interfere with each other whe ..."

The increasing density and data rate of unlicensed band wireless devices has led to significant inter- and intra-radio interference problems. Multiple competing standards such as the IEEE 802.11b/g, Bluetooth and ZigBee, all of which operate in the 2.4 GHz ISM band, can interfere with each other
Amplify-and-Forward Relaying for Reducing Outages in TDMA-Based WPANs Operating in Unlicensed Bands
"... Abstract — Diversity is of particular advantage for wireless personal area networks (WPANs) operating in unlicensed bands, as it may help to overcome not only channel fades but also cochannel interference. We consider WPANs based on time-division multiple access schemes leaving room for cooperative ..."

Peaceful Coexistence of IEEE 802.11 and IEEE 802.16 Standards in 5GHz Unlicensed Bands
"... Abstract—Cognitive radio devices have been considered as a key technology for next-generation of wireless communication. These devices in the context of IEEE 802.11 standards and IEEE 802.16 standards, can opportunistically utilize the wireless spectrum to achieve better user performance and improve ..."

and improve the overall spectrumutilization efficiency, mainly in the unlicensed 5 GHz bands. However, opportunistic use of wireless spectrum creates news problems such as peaceful coexistence with other wireless technologies, such as the radiolocation systems, as well as understanding the influence
