New wireless network paradigms will demand higher spectrum use and availability to cope
with emerging data-hungry devices. Traditional static spectrum allocation policies cause …

Cognitive radio sensor network (CRSN) is a combination of wireless sensor network (WSN)
and opportunistic spectrum access technology. It involves the issues related to energy and …

Cognitive radio sensor networks (CRSNs) are multi-channel-capable networks that inherit
some of the challenges of traditional wireless sensor networks (WSNs), such as limited …

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

In a realistic wireless network, all the unsuccessful transmission attempts are not due to
packet collisions only. But the transmission errors also played an important role because of …

Rendezvous is a process of two or more cognitive radio nodes gathering on the same
channel at the same time for a negotiation to establish data communications. This paper …

Many existing medium access control protocols for cognitive radio wireless sensor networks
waste bandwidth and suffer from delay because of the fixed channel negotiation period in …

This letter analytically shows the requirements of cross-layer-based routing in ad hoc
cognitive radio networks. This work estimates the number of channel switching in various …

A secondary user (SU) in multichannel cognitive radio ad hoc network (CRAHN) has a
limited transmission range, which may raise a hidden multichannel sensing problem. In …

In this paper, we consider underlay cognitive radio (CR) networks where an amount of
interference caused by secondary stations (STAs) has to be kept below a predefined level …
