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 …

We design a novel routing procedure for multihop cognitive radio networks composed of
adequate metrics and a strategy to combine these metrics. In cognitive radio networks …

With the growing spectrum demand over the last decade, the use of cognitive radio networks
(CRN) has provided a viable solution to spectrum scarcity problem. These networks …

In multi-hop cognitive radio networks, the communication links among the cognitive nodes
fail easily with the dynamic appearances of the licensed users. We propose an approach to …

Routing protocol is an important issue in cognitive radio networks. This paper explored the
issues and challenges of routing protocol in cognitive radio network from five aspects …

The emergence of cognitive radio network technology provides network nodes with
abundant licensed and unlicensed channels to select for routing. Traditional routing …

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 …

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 …
