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 …

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 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 …

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 …

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 …

The fixed spectrum allocation causes inefficient utilization of licensed spectrum bands, due
to which Cognitive Radio Networks (CRNs) emerged as a promising solution. Cognitive …

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 …

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 …

Jointly consider routing and spectrum selection is essentially and necessary in multi-hop
cognitive radio networks. System cost and throughput are commonly used to evaluate …

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 …
