support from the application layer. On the contrary, in the case of FTP, the vehicle would need to
collect specific packets (based on the predefined order) that may be hard to obtain from neighbor-
ing vehicles. In order to evaluate this capability of fountain, Figure 13.7 shows byte throughput of
the fountain and FTP algorithms. is metric is important since vehicles may be able to resume
the download some time later or from some other vehicles. As followed from the figure, the foun-
tain scenario’s throughput in terms of byte count is higher than the FTP scenario’s. Indeed, by
