The fixed spectrum allocation causes inefficient utilization of licensed spectrum bands, due
to which Cognitive Radio Networks (CRNs) emerged as a promising solution. Cognitive …

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 …

The ever-growing demand for higher network data rates, lower delay, and conservative
energy consumption at reduced costs, to support Internet-of-things (IoT) communications …

A cognitive radio (CR) is a radio that can change its transmission parameters based on the
perceived availability of the spectrum bands in its operating environment. CRs support …

Research studies in software maintenance are notoriously hard to reproduce due to lack of
datasets, tools, implementation details (eg, parameter values, environmental settings) and …

This study designs and presents routing protocols multi‐channel, multi‐hop cognitive radio
sensor network (CRSN), which are based on spectrum sensing, spectrum‐availability …

Routing is one of the major challenges in cognitive radio ad hoc networks. In finding new
routes, not only the less impacted paths due the primary user activity, but also bottleneck …

Cognitive radio networks (CRNs) have emerged as a paradigm addressing the problem of
limited spectrum availability and the spectrum underutilization in wireless networks by …

In a mobile ad hoc network, the data packet may fail to be delivered for various reasons
mostly for route failure, congestion, and battery energy drain. Hence, providing reliable and …

Abstract In Cognitive Radio Wireless Sensor Networks, the licensed spectrum bands are
highly dynamic, and their status varies overtime. With the expansion of these networks …
