Fault-Tolerant Wireless Consensus

Fault-tolerant wireless consensus systems face numerous challenges in practical applications, among which unstable communication poses a pivotal issue. Some prior works achieve consensus among all participating nodes by relying on a dependable wireless channel, e.g., (Yang et al., TUP Tsinghua Sci Technol 27(5):817–831, 2022) and (Xu et al., Consensus in wireless blockchain system, 2020). In contrast, real-world wireless networks contend with an unreliable and error-prone shared wireless channel. In a real wireless setting, the reliability and performance of the system can easily be affected by factors such as signal interference, node movement, device failures, insufficient signal coverage, and network congestion. These sources of unstable communication could lead to data transmission delays, increased packet loss, and even communication breakdowns, severely impacting the data consistency, real-time nature, and overall coordination capability of the system.
