A Group Mutual Exclusion protocol for the Use Case of IoT-Blockchain Integration In Work-Safe Scenario

Abstract

The Blockchain empowers IoT ecosystems more secure and transparent. AS a result, integrating these two technologies can have a significant impact across multiple industries. In this paper, a sample use case related to safe-work has been discussed. A group mutual exclusion (GME) protocol has been proposed for the consensus operation of different authorities/stakeholder to update the distributed ledger of the hybrid system. The protocol utilises a single token to enable various processes of different stakeholders to enter into a common session to reach the consensus among themselves. In other words, we have introduced a novel consensus protocol-proof of presence. The protocol offers a crucial characteristic-the concurrency, throughput, and waiting time can be tailored by adjusting the period for which a session is declared. The protocol also ensures no starvation in the system. Furthermore, this algorithm works out for the Extended Group Mutual Exclusion problem as well.
