Interest in the cognitive radio sensor network (CRSN) paradigm has gradually grown among
researchers. This concept seeks to fuse the benefits of dynamic spectrum access into the …

Cognitive Radio (CR) is a promising technology and innovative solution for current spectrum
allocation problems. We can exploit the unused licensed bands to meet the increased …

We propose a primary user-aware k-hop routing scheme that can be plugged into any
cognitive radio network routing protocol to adapt, in real time, to the environmental changes …

The CRN is a future generation wireless communication system that allows SUs to use the
underutilized or unused spectrum, known as white spaces, in licensed spectrum with …

In the scope of cognitive radio networks, typical routing protocols avoid areas that are highly
congested with primary users, leaving only a small fragment of available links for secondary …

A unique challenge for routing in cognitive radio networks is the collaboration between the
route selection and spectrum decision. To solve this problem, in this paper a Spectrum-Tree …

Cognitive radio networks (CRNs) have been emerging as a promising technique to improve
the spectrum efficiency of wireless and mobile networks, which form spectrum clouds to …

Designing an appropriate routing metric in cognitive radio networks (CRNs) is a challenging
problem. In a multi-hop CRN, both spectrum handoff (quantified by channel availability time) …

Cognitive radio sensor networks (CRSNs) are the next generation wireless sensor networks
(WSNs) that mitigate overcrowded unlicensed spectrum bands by opportunistically using …

Cognitive radio (CR) is the next-generation wireless communication system that allows
unlicensed users (or secondary users, SUs) to exploit the underutilized spectrum (or white …
