Cognitive radio (CR) networks are expected to offer a huge bandwidth to wireless users
through dynamic spectrum access techniques. To realize this new network paradigm …

Cognitive radio allows radio devices to access the idle spectrum opportunistically, thus
alleviates the huge demand for spectrum. Rendezvous, where two radios complete …

Rendezvous is a fundamental operation for cognitive users to establish communication links
so as to realize data communications and network management. Most of existing …

Transmitter power consumption and application throughput in cognitive radio-medium
access control (CR-MAC) protocol has direct impact on control message overhead and …

In this paper, we consider the problem of spectrum sharing in CRAHNs and propose a
distributed channel selection scheme. The key functionality of our proposal, best-fit channel …

Cognitive radio (CR) has been extensively investigated in the past decade to tackle the
contradiction between wireless spectrum shortage and underutilization. In this paper, we …

In order to increase channel usage efficiency, unlicensed users within a Cognitive Radio
Network (CRN) are permitted to utilize channels that are not currently occupied by licensed …

End‐to‐end application performance and throughput of vehicular cognitive transport control
protocol depend on how efficiently the segments (TCP header) are being transmitted from …

In cognitive radio networks (CRNs), two secondary users (SUs) need to meet on a channel
among multiple channels within a finite time to establish a link, which is called rendezvous …

Rendezvous is a fundamental operation in cognitive radio networks (CRNs) for establishing
a communication link on a commonly-available channel between cognitive users. The …
