This paper provides an overview of cognitive radio (CR) networks, with focus on the recent
advances in resource allocation techniques and the CR networks architectural design. The …

Fairness means to maintain the property of equity or equivalence. It is the distribution,
sharing, allocation, and supply of different working metrics fairly such as bandwidth …

In this work, we design a covert jamming scheme against an intelligent Eve towards physical
layer security in a cooperative cognitive radio networks. To protect the primary message …

A Wireless Sensor Network consists of a number of sensors. The energy of each sensor is
limited which limits network lifetime. There are many existing energy efficiency algorithms to …

Duty-cycle scheduling is an effective way to balance energy consumptions and prolong
network lifetime of wireless sensor networks (WSNs), which usually requires a connected …

Internet of Things (IoT) systems comprise massive volumes of smart devices. Through
exchanges of information, smart objects are capable of reasoning and generate higher level …

In this paper, we are interested in designing efficient distributed opportunistic routing
protocols for multi-hop multi-channel cognitive radio networks (CRNs). In CRNs, secondary …

A new network architecture, named as RF-based battery-free sensor network, was proposed
in recent years to overcome the lifetime limitation of traditional wireless sensor networks. In …

Data aggregation is a fundamental yet popular operation in wireless networks where the
sink needs to obtain the combined information of the whole network. However, the problem …

The social activities of Primary Users (PUs) and Secondary Users (SUs) affect actual
accessible whitespace in Cognitive Radio Networks (CRNs). However, the impacts of …
