IoT Monitoring with Blockchain: Generating Smart Contracts from Service Level Agreements

TL;DR

This paper proposes a blockchain-based approach for IoT service monitoring using smart contracts generated from SLAs, ensuring irrefutable evidence of violations and enhancing trust between providers and clients.

Contribution

It introduces a Java library that automatically generates smart contracts from SLAs and validates their effectiveness in a simulated IoT monitoring scenario.

Findings

100% success in capturing SLA violations in the mock scenario

Smart contracts provide tamper-proof evidence of violations

Enhances trust in IoT service monitoring using blockchain technology

Abstract

A Service Level Agreement (SLA) is a commitment between a client and provider that assures the quality of service (QoS) a client can expect to receive when purchasing a service. However, evidence of SLA violations in Internet of Things (IoT) service monitoring data can be manipulated by the provider or consumer, resulting in an issue of trust between contracted parties. The following research aims to explore the use of blockchain technology in monitoring IoT systems using smart contracts so that SLA violations captured are irrefutable amongst service providers and clients. The research focuses on the development of a Java library that is capable of generating a smart contract from a given SLA. A smart contract generated by this library is validated through a mock scenario presented in the form of a Remote Patient Monitoring IoT system. In this scenario, the findings demonstrate a 100 percent success rate in capturing all emulated violations.
