Cognitive radio (CR) is a promising technology that enables opportunistic using of the
unused spectrum to alleviate the spectrum scarcity problem. However, as the interference to …

Cognitive Radio (CR) is an emerging technology to deal with the shortcoming of today's
fixed spectrum management. In cognitive radio networks (CRN), a secondary user can …

In the distributed cognitive radio networks, users possess the ability to detect spectrum holes
to communicate with others which make the traditional routing protocol ineffective. The …

It has been more than a decade since the proposal of Cognitive Radio paradigm. Recently,
several researchers have started to work in the area of cognitive radio routing. In this paper …

Cognitive Radio (CR) has been recently proposed as a promising technology to remedy the
problems of spectrum scarcity and spectrum underutilization by enabling unlicensed users …

In CRAHNs (Cognitive Radio Ad Hoc Networks), cognitive users coexist with primary users
who have priority in accessing a set of licensed bands. Cognitive users can use those bands …

Cognitive Radio Networks (CRNs) increase spectrum utilization by opportunistically sharing
licensed spectrum with cognitive capable devices. There are many routing algorithms …

Cognitive radio (CR) technology is introduced to solve the problem of spectrum under-
utilization in wireless networks by opportunistically exploiting portions of the spectrum …

The cognitive radio (CR) nodes in a cognitive radio network (CRN) do not have license to
use specific spectrum band. Instead, they use the spectrum bands of the licensed primary …

(CR) has emerged as one of the most promising technology to overcome the inefficient
spectrum utilization problem. The basic intention behind CR is to opportunistically allow …
