On-demand content delivery in vehicular wireless networks

Abstract
We propose an information-sharing application for wireless intervehicular networks (IVNs), called Infoshare. The Infoshare application leverages the broadcast nature of the wireless medium to achieve maximum spreading of information queries among vehicles, while a smart caching policy limits the overhead resulting from useless queries and duplicated replies. Simulation by ns2 is used to investigate the performance of Infoshare, highlighting the impact of various system parameters on spreading dynamics. A network scenario featuring one- and two-lane traffic traveling either at the same or at different speeds is considered. Simulation results come in handy for the development of analytical models, identifying critical parameters and justifying assumptions.
