Contribution
It proposes a novel autonomous switch mechanism for distributed consensus that adapts to dynamic network conditions and fault types in wireless trustworthy systems.
Findings
D-CAST effectively switches between fault tolerance modes in dynamic environments.
The mechanism enhances system reliability under crash and Byzantine faults.
Implementation challenges of D-CAST in wireless systems are discussed.
Abstract
The protocols of distributed consensus normally aim to tolerate different types of faults including crash faults and byzantine faults that occur in the distributed systems. However, the dynamic network topology and stochastic wireless channels may cause the same trustworthy system to suffer both crash fault and byzantine fault. This article proposes the concept of a distributed consensus autonomous switch mechanism in trustworthy autonomous systems (D-CAST) to reach the different fault tolerance requirements of the dynamic nodes and discusses the challenges of D-CAST while it is implemented in the wireless trustworthy system.
