In cognitive radio networks, a cognitive source node requires two essential phases to
complete a cognitive transmission process: the phase of spectrum sensing with a certain …

Cognitive radio technique is applied to Vehicular Ad hoc Networks (VANET) to increase
frequency bandwidth. Spectrum sensing for opportunistic spectrum access is carried out …

Collaborative spectrum sensing is vulnerable to data falsification attacks, where malicious
secondary users (attackers) submit manipulated sensing reports to mislead the fusion …

Cognitive radio networks allow opportunistic spectrum access to the unlicensed users,
which rely on effective spectrum sensing. Recently, cooperative sensing has been found to …

Due to the huge number of diverse wireless devices and technologies, spectacular
increases in the number of wireless subscribers, advent of new applications and continuous …

This paper deals with spectrum sensing for cognitive radio scenarios where the decision
fusion center (DFC) exploits array processing. More specifically, we explore the impact of …

In this paper, we propose a two-phase protocol based on cooperative relaying for a
secondary system to achieve spectrum access along with a primary system. The primary …

In cognitive radio (CR) networks, the ability to capture a frequency slot for transmission in an
idle channel has a significant impact on the spectrum efficiency and quality of service (QoS) …

In this paper, we exploit cooperative spectrum sensing technique for applications in a relay
based cognitive radio network. Relays are assigned in cognitive radio networks to transmit …

In this paper, a reliable spectrum sensing (SS) scheme using dual detectors for IEEE 802.22
WRAN has been presented. In dual or double detectors, first one detector is energy detector …
