Extensive Throughput Enhancement For 5G Enabled UAV Swarm Networking

The ubiquitous deployment of 5G New Radio (5G NR) accelerates the evolution in many fields. With the enhancement of 5G NR, Unmanned Aerial Vehicle (UAV) swarm networking can gain more flexibility, reliability, and elasticity to assist residents or workers to finish missions of high complexity and risks remotely. The beamforming of 5G NR can improve the accuracy and the flexibility of connections between the mobile devices. With a high throughput guaranteed in the UAV swarm networking, the remote can deliver specific instructions with the high accuracy of requirement. Further, a reliable and high volume throughput assures multiple UAV swarm networking can exchange information to collaborate and cooperate underneath different mission allocations. In this paper, we propose a cell wall paradigm to escalate the flexibility and the throughput for the heterogeneous 5G enabled UAV swarm networking. With construction of cell wall, we formulate and summarize the throughput optimization into capacity maximal problem to achieve the max-min throughput. Thereafter, we implement an optimal edge coloring solution with the upper bound and the lower bound of color selection to schedule the orders of active links. Based on the optimal scheduling for each separate networking, we focus on the balance of the inter and intra active links to mitigate collisions on the UAVs to strengthen the throughput of UAV swarm networking for the collaboration and corporation of the heterogeneous UAV swarms on a large scale. The evaluation shows the optimal edge coloring approach can improve the throughput for UAV swarm networking at 73.8% maximally. With the optimal setting of ts=0.01s and tg=0.01s, we can achieve the optimal throughput for the collaboration of the heterogeneous UAV swarms globally.
