The great advances made in the wireless technology have enabled the deployment of
wireless communication networks in some of the harshest environments such as volcanoes …

Internet of things (IoT) paradigm poses new challenges to the communication technology as
numerous heterogeneous objects will need to be connected. To address these issues new …

The majority of work in cognitive radio networks have focused on single-hop networks with
mainly challenges at the physical and MAC layers. Recently, multi-hop secondary networks …

With the increasing demand for vehicular data transmission, limited dedicated cellular
spectrum becomes a bottleneck to satisfying the requirements of all cellular vehicle-to …

With growing interest in using cognitive radio (CR) technology in wireless communication
systems for vehicles, it is envisioned that future vehicles will be CR-enabled. This paper …

Since the introduction of the Internet in the 1970s of the past century, the concept of global
communications has notably changed our daily activities. Communication networks …

To resolve the contradictions between the increasing demand of vehicular wireless
applications and the shortage of spectrum resources, high mobility, short link lifetime, and …

In this paper, we investigate the opportunistic spectrum access for cognitive radio vehicular
ad hoc networks. The probability distribution of the channel availability is first derived …

Due to the highly dynamic nature of cognitive vehicular networks, several sporadic links
induce a long delay in the network. The selection of a stable route is therefore one of the key …

Abstract The aim of Intelligent Transportation Systems (ITS) is to automate the interactions
among vehicles and infrastructure to accomplish high levels of safety measures, comfort …
