Context and key aspects of the proposed PhD
In recent years, Inter-Vehicle Communication (IVC) has become an intense research area, as part of Intelligent Transportation Systems. It assumes that all, or, a subset of the vehicles is equipped with radio devices, enabling communication between them. This communication facility allows drivers to enhance more safety on roads by exchanging weather alerts, emergency alerts and traffic information. Another class of applications is to target the passengers access to Internet with all classical services: mail, web and chat. These communications are usually classified in two classes: Vehicle-to-Vehicle (V2V) or Vehicle-to- Infrastrcuture communications (V2I). V2V communications usually use ad hoc modes. This allows a vehicle to communicate directly with another vehicle without the use of any dedicated infrastructure (Base Station, Access Point, etc.). Although classical 802.11 can be used for IVC, specific technologies such as IEEE 802.11p (also referred to as Wireless Access in Vehicular Environments, WAVE) show a great deal of
promise. This standard includes data exchanges between vehicles and between infrastructure and vehicles with a greater radio range than classical 802.11. Also, by using ad hoc mode of these radio technologies (all the 802.11 technologies have an ad hoc mode), we gain the advantage that the scope of communications is not just limited to the radio range. Hence, vehicles can act as routers, i.e. they implement forwarding and routing algorithms, and form a Multi-Hop wireless Ad-hoc NETwork (MANET), also called Vehicular Ad hoc NETwork (VANET).
V2V communications are mainly intended for safety applications which consist either in periodic information broadcasting or in alert message dissemination. V2I communications uses existing cellular networks like UMTS or 4G/LTE or need deployment of a telecommunication network infrastructure, like WiMAX where some access points are distributed along the road, each one connected to other through a wired network allowing the vehicles to connect to the access point. V2I communications allows interesting user-oriented applications like “Internet on the road” or geographic information advertisements. The main drawbacks of a complete road coverage are prohibitive costs and inefficient use in case of light traffic. Then, a new class of communications has been proposed by telecommunication operators: V2V2I where vehicles communicate with other vehicles to reach the access point using multihop communications.
This work will consist in two parts. The first part will focus on the dissemination of warning and control information. This allows a vehicle to obtain and disseminate information about accidents, traffic jam, and road surface conditions coming from other vehicles. Such applications rely on broadcast algorithms. These algorithms are given the task of disseminating warning messages quickly and efficiently through the network. Thus, the performances of these algorithms are crucial. The second part will focus on V2V2I communications where keys questions are still open. For example, one possibility to provide the communications is to use a VANET with a routing protocol or to build a cluster of cars with only a leader connected to the infrastructure. As the communication device is equipped with multiple network interfaces that could be connected to different network providers and obtain multiple IP addresses, this multihoming feature can also provide an efficient way for mobility management. But due to intermittent connectivity, several problems has to be solved.
