With a rapid rise in the number of wireless devices and gadgets, a shortage in the spectrum
bands for wireless communications has been observed. To overcome this problem of …

In cognitive radio (CR), dynamic spectrum access (DSA) can be used for secondary user
(SU) to improve its spectrum efficiency under the limited spectrum resources. However, the …

With the steep increase in the number of vehicle users, the demand for channel resources is
increasing. However, the limited spectrum resources can't meet this huge demands. Using …

To solve the problem of spectrum scarcity and spectrum under-utilization in wireless
networks, we propose a double deep Q-network based reinforcement learning algorithm for …

High-speed rail public broadband wireless access requires communication terminals with
high mobility to perform seamless cell switching in a harsh and fast time-varying …

In order to meet the dramatic wireless bandwidth demands of emerging multimedia
applications, cognitive radio has been proposed as one of promising solutions to improve …

In traditional cognitive wireless network, most studies on spectrum allocation are on the
basis of static network topology. However, the vehicles in the cognitive vehicular network …

Traditional cognitive radio (CR) spectrum access techniques have been primitive and
inefficient due to being blind to the occupancy conditions of the spectrum bands to be …

This paper introduces a novel framework of coordinated spectrum sensing in cognitive-radio-
enhanced vehicular ad hoc networks (CR-VANETs). The proposed sensing coordination …
