Blockchain-Envisioned Softwarized Multi-Swarming UAVs to Tackle COVID-I9 Situations

With the spread of novel coronavirus, global health concerns have increased as it has flattened the curve of mortality worldwide. To handle such a containment of disease, multi-swarm Unmanned Aerial Vehicles (UAVs) with 5G can be used to reduce human intervention with major benefits of high bandwidth, ultra-low-latency, and reliability. Multi-swarm UAVs sends a huge amount of data to ground stations with real-time connection density of 107/km

, which is a bottleneck on 5G networks; data security is another issue in sharing sensitive data. Motivated by these issues, in this article, we propose a blockchain-envisioned softwarized multi-swarming UAV communication scheme based on a 6G network with intelligent connectivity, Terahertz (THz) frequency bands, and virtualization of link and physical-level protocols. Softwarization makes the communication infrastructure flexible, agile, and easily configurable, and the potential of blockchain supports data security. Results show that the proposed scheme performs better in terms of processing delay, packet loss reduction, and throughput compared to exiting 4G/5G-based systems.
