Description of the project, activities and work context

Communication needs for automotive applications will evolve and grow strongly with the arrival of Vehicular Ad-Hoc Network (VANET) and autonomous vehicles, which will enable the deployment of a wide variety of applications. While these new applications will focus on improving road safety and the comfort of users while traveling, new services will emerge such as platooning that will allow a vehicle with driver to guide autonomous vehicles assembled in a convoy on the urban network. The Internet of Things will further expand the scope of services offered. These applications, always more numerous, will have very different requirements in terms of quality of service (QoS) and security of the communications to which it will be necessary to answer. In particular, to become a reality on a daily basis, driving without a driver must be able to count on reliable means of communication at all times.

Radio access technologies that allow vehicles to communicate, either directly (V2V- Vehicle-to-Vehicle), or with a roadside communications infrastructure (V2I-Vehicle to Infrastructure), or directly with a network, are experiencing today considerable development with technologies such as ITS-G5 derived from Wi-Fi or Long Term Evolution (LTE). These developments will continue with the arrival of 5G NR, which should also standardize vehicle-to-vehicle (V2V) communications. Each of these technologies has particular characteristics such as bandwidth, radio range, availability and security, which are specific to it. Although specific bands are allocated for vehicular applications (ITS- Intelligent Transport System band), the coverage of a telecommunications network along roads and in low-density areas is far from complete because deployments are expensive. Cognitive radio (or Cognitive radio in English) is an emerging technology that will be able to detect unoccupied frequency bands and adapt its transmission parameters according to the constraints of communication in order to transmit in these bands. It will be able to use temporarily unused frequency bands in areas without communication infrastructure or in areas where radio traffic is low. In addition to being able to perceive and adapt itself to its environment, cognitive radio has reasoning and learning capabilities through the use of artificial intelligence technologies.

Objectives :

The aim of this thesis is to propose a solution that will allow the vehicle to select, in an autonomous way and in real time, the radio access technology (ies) that best meets the needs of road applications. In particular, it will be necessary to adapt the operation of cognitive radio so that it is able to select the best access technology (ies) in the presence of a certain number of constraints (quality of service, security, energy saving, etc.) and adjust the communication protocols and operational parameters accordingly. In addition, virtualization of network functions will facilitate the support of developments related to radio access technologies. The proposed solution will be validated by simulations and/or experimentations using a cognitive radio platform and considering different communication scenarios.
