Due to the broadcast nature of wireless networks, jamming attacks are inevitable. Therefore,
this paper considers enhancing the throughput of a primary user (PU) suffering from a …

This paper investigates the interactions between a secondary user (SU) with frequency
hopping and a jammer with spectrum sensing in heterogenous cognitive radio networks …

In cognitive radio networks with wireless energy harvesting, secondary users are able to
harvest energy from a wireless power source and then use the harvested energy to transmit …

Cognitive Radio (CR) provides a promising solution to the spectrum scarcity problem in
dense wireless networks, where the sensing ability of cognitive users helps acquire …

In this paper, we study the anti-jamming power control problem of secondary users (SUs) in
a large-scale cooperative cognitive radio network attacked by a smart jammer with the …

This letter studies the problem of deep reinforcement learning (DRL)-based dynamic
spectrum anti-jamming access in overlay cognitive radio networks. To prevent secondary …

We investigate the problem of dynamic spectrum anti-jamming access against intelligent
jammer using game theory and opponent modeling. Previous work has formulated the …

A cognitive radio network (CRN) is a novel solution that promises to solve the spectrum
scarcity problem and enhance spectrum utilization. However, unsecured CRN can easily be …

This paper introduces a machine learning based collaborative multi-band spectrum sensing
policy for cognitive radios. The proposed sensing policy guides secondary users to focus the …

Cognitive radio network is an intelligent wireless communication system which can adjust its
transmission parameters according to the environment thanks to its learning ability. It is a …
