With the rising demand for vehicular networking through wireless communication for safety
as well as non-safety applications, the urge to provide efficient bandwidth utilization along …

Nowadays detonation of holding vehicle has wrought overcrowded traffic. The US Federal
Communication Commission officially allocated nearly 75 MHz spectrum in 5.8 GHz band to …

Spectrum sensing is one of the fundamental functionality performed by a cognitive radio to
identify vacant radio spectrum for dynamic spectrum access (DSA). However, there are …

In this paper, we consider cooperative spectrum sensing when two secondary users (SUs)
collaborate via the relaying scheme. We investigate two cooperative sensing strategies, ie …

With the emergence of IoT and smart cities, wireless data traffic is exponentially increasing,
motivating telecom operators to search for new solutions. In this article, we propose a …

Cognitive Internet of Vehicles (CIoV) can improve spectrum utilization by accessing the
spectrum licensed to primary user (PU) under the premise of not disturbing the PU's …

In an interweave cognitive radio system, cooperative spectrum sensing has been
recognised as a key technology to enable secondary users to opportunistically access …

Cognitive radio (CR) is proposed as an efficient way to address the issue of spectrum
shortage and underutilization, in which cooperative spectrum sensing (CSS) is used to …

In vehicular ad-hoc network (VANET), the reliability of communication is associated with
driving safety. However, research shows that the safety-message transmission in VANET …

In this paper, an energy-efficient scheme is proposed for cooperative spectrum sensing in
cognitive sensor networks. In our scheme, we introduce a technique to select the sensing …
