Disclosed are a system, a computer-readable storage medium storing at least one program, and a computer-implemented method of data transmission. A communication module interfaces communicatively with vehicles. A file management module selects first data from a data queue. The first data is addressed to a destination location. The file management module transmits the first data to the first vehicle. The file management module receives an acknowledgement message from a second vehicle interfaced with the communication interface module. The acknowledgement message is indicative of the first vehicle providing the first data to a server at the destination location. The file management module deletes the first data from the data queue.
