The increasing demand for wireless communication introduces efficient spectrum utilization
challenge. To address this challenge, Cognitive Radio (CR) has emerged as the key …

Cognitive Radio (CR) is a promising technology to solve the spectrum scarcity. Spectrum
sensing becomes more challenging in Cognitive Vehicular Networks (CVNs) due to …

This paper introduces a novel framework of coordinated spectrum sensing in cognitive-radio-
enhanced vehicular ad hoc networks (CR-VANETs). The proposed sensing coordination …

Spectrum sensing is critical in allowing the cognitive radio network, which will be used in the
next generation of wireless communication systems. Several approaches, including …

To meet the dramatically increasing demands for vehicular communications, cognitive
vehicular networks have been proposed to broaden the vehicular communication bandwidth …

In this paper, we consider a cognitive radio wireless sensor network (CR-WSN), where each
sensor node is equipped with cognitive radio. A typical concern in CR-WSN is energy …

Spectrum sensing plays an important role in enabling cognitive radio technology for the up-
and-coming generation of wireless communication systems. Over the last decade, several …

Cognitive radio technology offers an important function in the efficient utilization of the radio
spectrum. Besides, it is expected that CR-enabled vehicular ad-hoc networks (CRVANETs) …

The cognitive radio (CR) network consists of primary users (PUs) and secondary users
(SUs). The SUs in the CR network senses the spectrum band to opportunistically access the …

In cognitive vehicular networks, unlicensed secondary users heavily depend on spectrum
sensing to find unused spectrum bands for communications. The performance study of …
