5G-enabled Optimal Bi-Throughput for UAS Swarm Networking

Unmanned Aerial Systems (UAS) swarms are being deployed in many applications to complete challenging missions with the requirements of flexibility, complexity, and accuracy successfully. With 5G New Radio (5G NR), UAS swarm networking can yield high capacities of mobile communication to provide more stable, effective services for UAS swarm. However, the conventional architectures of UAS swarm networking are centralized and hierarchical, thus restricting the high volume communication due to heterogeneous swarm communication, and the deployment of UAS swarms on a large scale. In this paper, inspired by the behavior of cell communication, we propose a cell wall oriented bi-throughput optimization algorithm for UAS swarm networking. To be specific, We leverage edge-coloring to optimize the routing schedule to obtain the maximum throughput for each UAS swarm. The evaluation shows that the throughput from both directions can be enhanced to achieve an improvement of up to 90% when the time slot is less than 0. 01s. The 5G-enabled optimal bi-throughput solution shows great potential to provide UAS swarm networking more compatible capacities for the challenging mission in real-time.
