Cognitive radio networks (CRNs) are composed of cognitive devices capable of changing
their configurations on Real time, based on the spectrum environment. This capability …

Cognitive radios are recommended by FCC as a countermeasure against spectrum scarcity
and inefficient utilization of spectrum. A cognitive radio can opportunistically use temporally …

Cognitive Radio Ad-Hoc Network (CRAHN) is an emerging class of mobile ad hoc networks
that provides each network node with a list of available channels. It is expected that the …

Cognitive Radio Network (CRN) introduced to solve the problem of spectrum scarcity by
taking advantage of the unused spectrum. Cognitive Radio Adhoc Networks (CRAHNs) …

Cognitive radio ad hoc networks can be used to solve the problems of limited available
spectrum and inefficient spectrum usage by adaptively changing their transmission …

Cognitive radio has become a promising technology in recent times as it facilitates the
opportunistic use of the frequency spectrum, a precious resource in the communications …

Ad-hoc routing protocols with cognitive capabilities have been proposed which solves the
problem of spectrum scarcity. It does it by intelligently allowing the unlicensed devices to …

Unpredictable channel availability in cognitive radio networks (CRNs) account for routing
