Vehicular Ad Hoc Networks are networkscharacterized by intermittent connectivity and rapid changes in their topology. This paper addresses car-to-road communicationsin which vehicles use Access Points (AP) in a Delay Tolerant Network architecture. Results show how the combination of aDelay-Cooperative ARQ mechanism reduces packet losses and in conjunction with a Carry-and-Forward cooperative mechanismimproves performance parameters in terms of total file transfer delay and number of AP needed to download files.
