Unmanned aerial vehicles (UAVs) have gained popularity for diverse applications and
services in both the military and civilian domains. For cooperation and collaboration among …

The problem of channel quality prediction in cognitive radio networks is investigated in this
paper. First, the spectrum sensing process is modeled as a Non-Stationary Hidden Markov …

The benefits of cognitive radio networking (CRN) have been well recognized with the
emerging wireless applications in recent years. While many existing works assume that the …

Integrated frameworks have extended the applications of networks beyond a simple data
sharing unit. Simultaneously, operating networks can form a layered structure that can …

In this paper, we consider the problem of cooperative spectrum sensing scheduling (C3S) in
a cognitive radio network (CRN) when there exist multiple primary channels. Our work …

In cognitive radio ad hoc networks (CRAHNs), the secondary users' links are interrupted by
the arrival of primary users, which leads to a significant increase of the number of …

Multiple-Input Multiple-Output Cooperative Cognitive Radio Networks (MIMO-CCRNs) have
been proposed recently to further improve the spectrum efficiency. In MIMO-CCRNs …

Spectrum sensing is considered as the cornerstone of cognitive radio networks (CRNs).
However, sensing the wide-band spectrum results in delays and resource wasting …

Cooperative cognitive radio networks (CCRNs) enable secondary users (SUs) to access
primary resource by cooperation with active primary users (PUs). For the cooperation …

Intra-cell interference management is one of the technical challenges for device-to-device
(D2D) communication underlaying cellular networks. In this paper, we propose two …
