Reactive handover coordination system with regenerative blockchain principles for swarm unmanned aerial vehicles

Aerial warfare systems in various countries highly expect Swarm Unmanned Aerial Vehicles (UAVs) and Flying Adhoc Networks (FANETs) for defense stability. However, swarm UAVs face many challenges, like security breaches, malfunctions, link failures, and handover failures. UAVs can easily malfunction by external threats to create data loss, theft, signal jamming, misrouting, false handover, and location spoofing. Failures in UAV handover principles make overall gradual downtime in FANET. Against these issues, existing UAV protection mechanisms deliver location monitoring mechanisms (graphs and trees), multi-link handover mechanisms, and distributed authentication principles. However, the implantation of recent-day techniques may fail against migrating attacker events executed in electronic warfare systems. The existing security methods need improvements for protecting Multi-UAV layers effectively through end-to-end security principles. For this purpose, a new Reactive Handover Coordination System with Regenerative Blockchain (RHCRB) Principles is proposed that takes novel high-security features specially made for swarm UAVs. The proposed RHCRB implements more crucial distributed functions in each UAV on demand. The executed operations of RHCRB comprise trusted location monitoring schemes (internal and cooperative UAV movements), dynamic location-based cost magnitude calculations, regenerative blockchain principles (authentication of each UAV and active edges), confidential link management principles, secure handover coordination, and on-demand topology management principles. The technical aspects of RHCRB build lightweight and shielded handover principles against airfield vulnerabilities. The proposed model suggests implementing an entirely protected handover environment from node localization to handover events. The inspired technical aspects of RHCRB contribute to the swarm UAV environment through confidentiality using Advanced Encryption Standard (AES) and distributed authentication (blockchain-based node and edge management) principles to engage protected handover practices. The experimental section of this article has been tested using testbed in FlyNetSim tool for implementing RHCRB and notable recent security techniques such as the Internet of Vehicles with Decentralized Blockchains (IoV-DB), Group Handover for Internet of Defense (GH-IoD), and Handover and Optimized Security Principles for UAVs (HOOPOE). The results obtained by this system show RHCRB's 8% to 14% of betterment than existing techniques through various measures.
