In this paper, a route selection mechanism for cognitive radio network (CRN) is proposed
where the route construction process selects only those channels which have the maximum …

To resolve the issue of efficient spectrum allocation, a precious resource in communication
systems, Cognitive Radio Adhoc Networks were proposed. Cognitive Radio Networks …

Cognitive Radio is devised as a wireless communication technology that enables user to
communicate without having a fixed pre assigned radio spectrum. The technology facilitates …

In this paper, we propose a flexible and resilient communication system using an ad-hoc
cognitive radio network that fully utilizes the available spectrum resources. Two main issues …

Cognitive radio technology is a new design paradigm for next-generation wireless networks
which aims to provide dynamic utilization of the scarce radio spectrum. The cognitive radio …

Cognitive radio is a dynamic technology that has a potential of addressing the spectrum
scarcity challenge. However, routing in cognitive radio network is a challenge. The …

In the past few years, cognitive radio paradigm emerged as a solution to avoid problems of
spectrum scarcity and inefficiency in spectrum usage. Cognitive Radio (CR) capable to …

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 …

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 …

Cognitive radio networks are composed of spectrum-agile devices capable of changing their
configurations and transmission parameters on the fly based on their spectral environment …
