Achieving High Throughput Ground-to-UAV Transport Via Parallel Links

Wireless data transfer under high mobility, as found in Unmanned Aerial Vehicle (UAV) applications, is a challenge due to varying channel quality and extended link outages. The authors present FlowCode, an easily deployable link-layer solution utilizing multiple transmitters and receivers for the purpose of supporting existing transport protocols such as TCP in these scenarios. By using multiple transmitters and receivers and by exploiting the resulting antenna beam diversity and parallel transmission effects, FlowCode increases throughput and reception range. In emulation, they show that TCP over FlowCode gives greater goodput over a larger portion of the flight path, compared to an enhanced TCP protocol using the standard 802.11 MAC.
