Back to basics: road traffic in vehicular networking

Marco Fiore

Abstract: The representation of road traffic is a paramount factor in the design, dimensioning and evaluation of network solutions intended for vehicular environments. The macroscopic dynamics of vehicular flows and the microscopic behavior of drivers have a major impact on both infrastructured access networks for automobile users (in terms of deployment and dynamic resource allocation) and spontaneous and/or opportunistic vehicle-to-vehicle networking (in terms of network connectivity over time and space).
In this talk, I will outline an history and state of the art of the multifaceted way vehicular mobility is portrayed in the vehicular networking literature. I will then address the problem of the impact that such a mobility representation has on the network performance. Finally, I will provide a summary of the open problems and a vision of the future evolutions on the topic of integrating road traffic in vehicular networks.
