Measurement results for file transfer using RaptorQ in a mobile environment

We report the results of a limited number of measurements that were performed to compare the upload performance of a RaptorQ-based file transfer protocol to SFTP in a mobile environment. In particular, we measured times required to transfer files from a laptop in a vehicle and tethered to the Internet via an iPhone hotspot to a stationary host located on the Internet and having a manually assigned IP address. Even though our RaptorQ-based protocol is in its very early stages of development, we found that the file transfer times of the two protocols are comparable in the stationary environment even without doing any specific optimization work on the RaptorQ-based protocol. We also found that SFTP was very prone to stalling whenever we passed through a region where propagation is poor whereas, in the same propagation environment, the RaptorQ-based protocol tended to make use the available bandwidth and complete the file transfer but with a reduced file transfer time.
