Multimedia and delay-sensitive data applications in cognitive radio sensor networks (CRSN)
require efficient real-time communication and dynamic spectrum access (DSA) capabilities …

The author presents a unified treatment of this highly interdisciplinary topic to help define the
notion of cognitive radio. The book begins with addressing issues such as the fundamental …

Cognitive Radio (CR) networks allow users to opportunistically transmit in the licensed
spectrum bands, as long as the performance of the Primary Users (PUs) of the band is not …

The routing procedure in cognitive radio networks with dynamic spectrum activities is
studied. The spectrum statistics are assumed to be unknown. Moreover, the performance is …

In cognitive radio networks (CRNs), secondary users must be able to accurately and reliably
track the location of small-scale mobile primary users/devices (eg, wireless microphones) in …

Wireless LANs (WLANs) have been widely deployed as edge access networks that provide
the important service of Internet access to wireless devices. Therefore, performance of end …

In this paper, we investigate the TCP throughput performance enhancement for cognitive
radio networks (CRNs) through lower-layer configurations. There is an interaction between …

The Transmission Control Protocol (TCP) is a very popular transport protocol used by the
majority of applications. However TCP is inefficient when used over mobile networks …

Abstract Dynamic Spectrum Access (DSA) allows unlicensed wireless devices to
opportunistically access unoccupied licensed spectrum bands. DSA yields efficient spectrum …

认知无线网络中, 认知用户需要具备频谱感知的功能, 在主用户到来时, 可以实现动态频谱切换,
从而不影响主用户的通信. 但是频谱感知和切换带来的时延可能使认知用户TCP …
