Throughput Performances of UAV Multi-Hop Communications by Applying Link Adaptation

Abstract

Although unmanned aerial vehicle (UAV) multi-hop network is effective to establish communications between a base station and remote harvesting robots with long distances, the studies of it have been limited to its information delivery time under delay tolerant networking (DTN) concept. In this paper, we focus on studying connection time between UAV and base station/harvesting robot, and link adaptation is used to increase the throughput performances. In this paper, the uplink throughput from the remote harvesting robot to the base station when applying link adaptation is numerically clarified through computer simulations.
