Description
This comprehensive survey examines consensus al-
gorithms utilized in Distributed Ledger Technology (DLT) for
Internet of Things (IoT) environments. The paper provides a
comparative analysis of consensus protocols including Proof of
Work, Proof of Stake, Proof of Authority, Proof of Elapsed Time,
Proof of Space, Proof of Activity, Practical Byzantine Fault Tol-
erance algorithm and Directed Acyclic Graph based approaches
such as Adaptive Proof of Work, and Temporal Proof. These
algorithms are evaluated against critical metrics for IoT contexts:
energy efficiency, transaction throughput, scalability, latency,
and security guarantees. The survey highlights fundamental
trade-offs between decentralization, security, and performance
in DLT implementations, with particular focus on mechanisms
compatible with resource-constrained IoT networks. Through
this systematic comparison, the paper provides a comprehensive
overview of the suitability of various consensus mechanisms
within IoT-oriented distributed ledger systems.
