The emerge of Internet of Things (IoT) brings up revolutionary changes to wireless
communications. Cognitive radio (CR) can be seen as one of the prominent solutions to …

Multi-band cooperative spectrum sensing can provide access to a wide range of spectrum in
cognitive radio networks (CRNs). The design of multi-band spectrum sensing is very …

Multi-band cooperative spectrum sensing (CSS) can provide opportunistic spectrum access
to secondary users (SUs) in cognitive radio networks (CRNs). In multi-band CSS, the …

In this work, we propose a distributed cooperative spectrum sensing (CSS) scheme for
cognitive radio networks applying a greedy-based coalitional game. We formulate the …

Most cooperative spectrum sensing research activities focus on maximizing the primary user
detection and neglect the achieved secondary system performance. This paper proposes a …

Cognitive radio networks (CRNs) can greatly improve the temporal and spatial spectrum
utilization by identifying and exploring spectrum holes of the licensed primary users (PUs) …

In this paper, we consider a multichannel cognitive radio network, where cooperative
secondary users have heterogeneous sensing ability in terms of their sensing accuracy. We …

A cognitive radio (CR) network consists of wireless devices that opportunistically borrow
vacant licensed bands. Cognitive users adaptively employ a perception-action decision …

In cooperative spectrum sensing (CSS), a multibit combination rule shows better sensing
performance than one-bit hard combination rules at the sacrifice of the reporting overhead …

A large number of previous works have demonstrated that cooperative spectrum sensing
(CSS) among multiple users can greatly improve detection performance. However, when the …
