In this paper, a novel opportunistic spectrum sharing scheme, based on orthogonal
frequency division multiplexing with index modulation (OFDM-IM), is proposed for cognitive …

In this paper, we address the challenging and important cooperative spectrum sensing
(CSS) problem with M-ary quantized data under spectrum sensing data falsification (SSDF) …

The security issue in collaborative sensing in cognitive radio networks can be modeled as
attackers and secondary users in a jamming and anti-jamming scenario. In this paper, we …

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

Cognitive radio is a revolutionary paradigm to migrate the spectrum scarcity problem in
wireless networks. In cognitive radio networks, collaborative spectrum sensing is considered …

Collaborative spectrum sensing improves the spectrum state estimation accuracy but is
vulnerable to the potential attacks from malicious secondary cognitive radio (CR) users, and …

Measurements on radio spectrum usage have revealed an abundance of under-utilized
bands of spectrum that belong to primary (licensed) networks. Prior knowledge about the …

In cognitive radio cooperative communication (CR-CC) systems, the achievable data rate
can be improved by increasing the transmission power. However, the increase in power …

This comprehensive reference text discusses concepts of cognitive radio and the advances
in the field of spectrum sensing. This text discusses the concept of cognitive radio for next …

Spectrum sensing is a key problem in cognitive radio (CR). Because of a low SNR, fading
and sensing time constraints, a single CR may not be able to reliably sense the presence of …
