Cognitive radios hold tremendous promise for increasing spectral efficiency in wireless
systems. This paper surveys the fundamental capacity limits and associated transmission …

In this paper, we consider a cognitive radio (CR) network where a secondary (cognitive)
user shares the spectrum for transmission with a primary (non-cognitive) user over block …

This paper studies the information-theoretic limits of a secondary or cognitive radio (CR)
network under spectrum sharing with an existing primary radio network. In particular, the …

We study a cognitive network consisting of a single primary transmitter and multiple
secondary, or cognitive, users. The primary transmitter, located at the center of the network …

In this paper, we study the denial-of-service (DoS) attack on secondary users in a cognitive
radio network by primary user emulation (PUE). Most approaches in the literature on primary …

With the increasing demands on frequency resources, spectrum sharing between the
satellite and terrestrial systems becomes prominent, especially when it comes to the …

Written in a unique style, this book is a valuable resource for faculty, graduate students, and
researchers in the communications and networking area whose work interfaces with …

Two distinct, but overlap**, networks that operate at the same time, space, and frequency
is considered. The first network consists of n randomly distributed primary users, which form …

We study the scaling laws for the throughputs and delays of two coexisting wireless
networks that operate in the same geographic region. The primary network consists of …

Cognitive radio networks (CRNs) have the potential to utilize spectrum efficiently and are
positioned to be the core technology for the next-generation multihop wireless networks. An …
