Hybrid aerial-terrestrial communication networks based on low-altitude platforms are
expected to meet optimally the urgent communication needs of emergency relief and …

The author presents a unified treatment of this highly interdisciplinary topic to help define the
notion of cognitive radio. The book begins with addressing issues such as the fundamental …

Cognitive radio (CR) enables dynamic spectrum access (DSA). In CR networks (CRNs),
unlicensed cognitive users (CUs) can share the radio spectrum with the licensed primary …

Localization of primary users (PUs) is a feature that can be very helpful for all the functional
tasks of a cognitive radio (CR) network. Among the possible algorithms, weighted centroid …

This paper is proposing a novel concept of Cognitive Relay Node for intelligently improving
the radio coverage of an airborne LTE emergency network, considering the scenarios …

In this paper we address the deployment of a temporary cognitive secondary LTE Femtocell
network in order to supplement and enhance the coverage of a regular LTE network for …

Dedicated Short-Range Communications (DSRC) technology in the 5.8 GHz band is a key
enabler to support a safer and more efficient vehicular transportation in the future. The …

In this paper, we investigate localization techniques based on direction-of-arrival (DoA)
measurements to estimate the position of primary users in cognitive radio networks. In the …

The Automatic Identification System (AIS) is used worldwide as a maritime system for
identifying and locating vessels by exchanging data in Very High Frequency (VHF) band …
