Study Notes

LH-Raft Protocol

LH-Raft protocol is designed to optimize consensus processing in large IoT applications.
It reduces communication cost, consensus latency, and agreement time.
LH-Raft achieves scalability by partitioning the blockchain network into a hierarchical architecture and reducing the size of the candidate group.
Compared to the original Raft protocol, it achieves consensus faster with reduced network overhead and communication cost.
The protocol uses a Location-based Hierarchical Raft algorithm (LH-Raft) mechanism, which forms localized consensus candidate groups based on reputation scores and geographic information to elect leaders.
Numerical analyses based on the LH-Raft protocol, with the candidate group formation and message passing model, indicate its scalability and suitability for large-scale and real-world IoT applications.

Study Objective

The study aims to create a new consensus protocol specifically for IoT-blockchain applications.
The protocol will be hierarchical and location-aware.
This design aims to overcome the scalability and computational cost challenges of existing consensus protocols.
It will ensure that IoT-blockchain applications can function efficiently and effectively.
