A large number of smart devices in Internet of Things (IoT) environments communicate via
different messaging protocols. Message Queuing Telemetry Transport (MQTT) is a widely …

Cognitive radio network (CRN) is a pioneering technology that was developed to improve
efficiency in spectrum utilization. It provides the secondary users with the privilege to …

The growing number of radio communication devices and limited spectrum resources are
drivers for the development of new techniques of dynamic spectrum access and spectrum …

A novel spectrum sensing algorithm based on support vector machine is proposed. The idea
is to map the received signals into a multi-dimensional feature space obtained from well …

Abstract The 5th generation (5G) of wireless systems is being deployed with the aim to
provide many sets of wireless communication services, such as low data rates for a massive …

Cognitive Radio is an intelligent wireless communication system able of learning from the
environment. It allows reusing of the radio resources available by users called Secondary …

This paper surveys Artificial Intelligence (AI) methods for acquiring and managing context-of-
operation awareness of radio communication nodes, links, and networks. The meaning and …

In this paper, a cooperative Secondary Network (SN) is proposed that operates under a
hybrid underlay-interweave model. The narrowband sensing problem under the interweave …

The fast growth of wireless technology in today's scenario has paved huge demand for
licenced and unlicenced frequencies of the spectrum. Cognitive radio will be useful for this …

In order to improve the spectrum sensing (SS) performance under a low Signal Noise Ratio
(SNR), this paper proposes a supervised learning spectrum sensing method based on …
