Routing in a cognitive radio network operating in a dynamic environment is a complex
decision problem. Diversity in the number of available spectrum bands and their stability, in …

Adaptability and accuracy in decision making of routing protocols play an important role in
the performance of the network. This role is even more crucial in a cognitive radio mesh …

Cognitive radio networks (CRNs) are networks of nodes equipped with cognitive radios that
can optimize performance by adapting to network conditions. Although various routing …

The erratic nature of spectrum availability and diversity imposes the use of a probabilistic
framework for channel selection in cognitive radio networks protocol design. In this work, two …

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 …

We present a new routing paradigm for cognitive radio networks that computes paths from a
source to a destination by considering t he activity and the placement of primary users. Our …

Cognitive radio (CR) technology is a new communication paradigm that can be a solution for
the spectrum scarcity problem. A new open spectrum operation necessitates a novel routing …

Nodes in Cognitive radio networks can change their communication frequency actively,
which affects networks topology and routing. In this paper, a joint routing and spectrum …

Cognitive radio networks represent a new class of wireless networks where the channels
are not permanently available, depending on the traffic activity of licensed users who have …

In this paper, cognitive radio network is briefly introduced as well as routing parameters in
cognitive radio networks. Due to lack of Spectrum, using not efficient methods of allocating …
