We propose a new local spectrum knowledge-based minimum channel switch routing
(MCSR) protocol for cognitive radio ad hoc networks (CRAHNs). CRAHNs have a mix of …

Cognitive radio networks are emerging kind of wireless networks with cognitive radio nodes
able to have dynamic spectrum access in order to make use more efficiently of the spectrum …

Cognitive radio (CR) is a promising technology geared to solve the spectrum scarcity
problem by opportunistically identifying the vacant portions of the spectrum and transmitting …

Cognitive radio has recently emerged as a promising technology to promote the utilization
efficiency of the existing radio spectrums allocation. In cognitive radio ad hoc networks …

Cognitive radio networks improve spectrum utilization by‎ sharing licensed spectrum with
cognitive radio devices. In‎ cognitive radio ad hoc networks the routing protocol is one‎ of the …

Cognitive radio network has received increasing attention in recent few years. A unique
challenge for routing in cognitive radio networks is the collaboration between the route …

Routing is an important issue in cognitive radio ad hoc networks (CRAHNs) owing to the
stochastic activity of primary users (PUs). In particular, route stability remains an important …

The rapid demand for wireless communication networks in the last few decades has lead to
spectrum scarcity, Hence there is need of efficient spectrum utilization is occurs. Cognitive …

Cognitive radio network is a new emerging research area recently. It enhances the existing
software-defined radio [1], whose physical layer behaviour is largely defined in software …

Recent research in the emerging field of cognitive radio (CR) has mainly focused on
spectrum sensing and sharing, that allow an opportunistic use of the vacant portions of the …
