Abstract
A system and method of wirelessly communicating data originating at a central facility between a plurality of vehicles using vehicle-to-vehicle short-range wireless communications includes wirelessly receiving, at a seed vehicle, one or more data files that have been encoded into data chunks from a central facility; storing the data chunks included in the received data file(s) at the vehicle; receiving interest messages for the data file(s) at the seed vehicle from each of a plurality of other vehicles via a short-range wireless broadcast, wherein the interest messages include one or more data file names and, for each data file name, the identity of the data chunks requested; identifying data files and data chunks existing in more than one received interest message; and transmitting the data chunks to the plurality of vehicles via the short-range wireless broadcast.
