10.1. Introduction

Vehicular communication needs will evolve and experience a boom due to the ascent of connected and autonomous vehicles (AV). Connectivity of various types such as vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and more broadly vehicle to X enables the deployment of a wide variety of applications aiming first of all to improve road safety, and also user comfort during travel. In the context of AVs, new services will emerge, such as platooning, which enables a human-driven car to guide AVs gathered in a convoy through the urban network. Car sharing and the Internet of Things will further broaden the range of services offered. Although currently few, these applications will have various demands in terms of quality of service (QoS) and communications security, which will need to be addressed. Communication link reliability will require self-adaptation of radio access technology, which is made possible by cognitive radio (CR), a technology that is able to detect free frequency bands and adapt its transmission parameters to communication needs and constraints. This concept was introduced by Mitola and Maguire (1999).

CR is defined by its perception, adaptation ...
