The rapid development of wireless traffic pushed the wireless community to research
different solutions towards the efficient utilization of the available radio spectrum. However, a …

In cognitive radio (CR) ad-hoc network, the characteristics of the frequency resources that
vary with the time and geographical location need to be considered in order to efficiently use …

This paper introduces a machine learning based collaborative multi-band spectrum sensing
policy for cognitive radios. The proposed sensing policy guides secondary users to focus the …

In the existing network‐layered architectural stack of Cognitive Radio Ad Hoc Network
(CRAHN), channel selection is performed at the Medium Access Control (MAC) layer …

In this paper, we examine the problem of network management for cognitive radio ad hoc
networks.(CRAHNs). A cognitive radio (CR) is an intelligent wireless communications device …

This paper introduces the self-organizing dynamic spectrum management (SO-DSM) for ad
hoc cognitive radio (CR) networks. In this scheme, CR units try to exploit the primary …

A cognitive radio (CR) is a promising technology to solve the emerging spectrum crisis,
especially for applications where thousands of wireless sensor nodes are deployed. Since …

Cognitive radio technology is an assuring solution for under-utilization of licensed spectrum
bands and overcrowding of unlicensed spectrum bands, in which secondary user is …
