This paper assesses the communication link from smart meters to aggregators as
(unlicensed) secondary users that transmit their data over the (licensed) primary uplink …

To mitigate spectrum scarcity, the cognitive radio (CR) paradigm has been invoked for
improving the overall exploitation of the licensed spectrum by identifying and filling the free …

The opening of TV white space (TVWS) bands for cognitive access is one of the first tangible
steps to solve spectrum scarcity problem in current wireless networks. However, this has …

In cognitive radio network (CRN), the secondary user (SU) opportunistically access the
wireless channels whenever they are free from the licensed/primary user (PU). Even after …

In this study, a new network architecture based on the software‐defined networking (SDN)
approach is proposed for cognitive radio networks (CRNs). The proposed network …

In this paper, we propose a semi-distributed cooperative spectrum sensing (SDCSS) and
channel access framework for multi-channel cognitive radio networks (CRNs). In particular …

We provide a comprehensive delay and queueing analysis for two baseline medium access
control protocols for multi-user cognitive radio networks with homogeneous users and …

M2M communications enables devices with an ability to communicate autonomously and
thus acts as the enabling technology for Internet-of-Things. It is expected that a multitude of …

Rapid progress in software, hardware, mobile networks, and the potential of interactive
media poses many questions for researchers, manufacturers, and operators of wireless …

Cognitive radio networks (CRNs) have emerged as a promising paradigm that can solve the
shortage of spectrum resources, providing the ability to adapt and opportunistically exploit …
