We propose a novel graph theoretic matching algorithm to model the dynamic channel
allocation problem in cognitive radio networks. In the past, no research work has considered …

In cognitive radio (CR) networks, due to the uncertainty of primary users'(PUs) traffic, there
are vacant bandwidths that can be accessed by secondary users (SUs). Thus, this provides …

The constraints of genetic spectrum assignment model without co-channel interference in
cognitive radio networks are analyzed in this paper. An improved genetic spectrum …

The rising density of wireless devices, combined with the availability of a plethora of wireless
web applications, has overcrowded the radio frequency spectrum. Majority of the present …

In this paper, a novel spectrum allocation approach for cognitive radio networks (CRNs) is
proposed. Based on a measure of inference performance as well as on a measure of quality …

In this paper, we propose a Swarm Intelligence based Resource Allocation Algorithm
(SIRAA) for optimum allocation of available spectrum holes to cognitive radio users. Usage …

In this paper, we propose a novel simple heuristic algorithm for scheduling the secondary
link activation and provide a dynamic spectrum sharing in cognitive radio networks. This …

Cognitive radio (CR) technology is a promising technology that provides opportunistic
access to free channels for secondary users (SUs), and enhances the spectrum efficiency. In …

In this work, we use game theory to analyze the spectrum allocation problem of cognitive
radio networks. To deal with the multi Nash equilibrium problem of non-cooperative game …

In Cognitive Radio (CR) networks, the licensed but vacant spectrum bands are assigned to
the CR users in an opportunistic manner. These assignments should be realized according …
