Lookup Table Designs for Real-Time RAFT Consensus Agreements on HAPS Platforms

Yuqiang Wen, K. L. Eddie Law

High-Altitude Platform Station (HAPS) Mesh networks hold promise for delivering high-availability wide-area network services, enabling real-time RAFT in distributed systems. However, the dynamic nature of HAPS networks disrupts RAFT's critical performance metric—the 95th percentile commit time—which directly impacts service level agreements (SLAs). …
