In this paper, we study resource management and allocation for energy harvesting cognitive
radio sensor networks (EHCRSNs). In these networks, energy harvesting supplies the …

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

The problem of channel quality prediction in cognitive radio networks is investigated in this
paper. First, the spectrum sensing process is modeled as a Non-Stationary Hidden Markov …

The cooperation between the primary and the secondary users has attracted a lot of
attention in cognitive radio networks. However, most existing research mainly focuses on the …

In this article, the authors proposed a novel blockchain‐oriented location privacy‐preserving
(BoLPP) for the Cooperative Spectrum Sensing (CSS) in 6G networks. In order to attain the …

Most previous spectrum sensing techniques use omni-directional antennas. Unlike omni-
directional antennas, the use of directional antennas for spectrum sensing is a promising …

Cognitive radio (CR) has emerged as one of the most promising candidate solutions to
answer the spectrum scarcity problem. Spectrum sensing is an essential task in improving …

In this paper, we investigate a covert cooperative cognitive radio (CCCR) system, where
multiple primary transmitters (PTs) transmit information with the aid of multiple secondary …

At present, the demand for wireless communications is growing tremendously. Cognitive
radio network plays an important role in making the spectrum to be used effectively …

Spectrum sensing is considered as the cornerstone of cognitive radio networks (CRNs).
However, sensing the wide-band spectrum results in delays and resource wasting …
