Assessing the VANET's Local Information Storage Capability Under Different Traffic Mobility
Wireless networking enabled vehicles can form Vehicular Ad hoc Mesh Networks (VMesh). By cooperative communication among VMeshes, a local transient information could be "Retained" within a given geographic region for a certain period of time, without any infrastructure help. In this paper, the authors study this "Storage Capability" of VMesh. The authors analyze the scenarios of highway traffic (both one-way and two-way highway free flow traffic), and vehicular traffic in a city environment. For highway traffic, they study different properties of the "VMesh Storage", using a simulation tool that accurately models the freeway vehicular mobility. For city traffic, they first perform simulations based on real traffic trace of San Francisco Yellow Cabs.
