IoT and Blockchain for Smart Water Quality Management in Future Cities: A Hyperledger Fabric Framework for Smart Water Quality Management and Distribution

Abstract

Abstract The delivery and management of clean water are crucial for the long-term growth of Smart Cities. However, controlling water quality and delivery in a smart city is a difficult and time-consuming process. In this work, we suggest a unique solution for smart water quality monitoring and distribution in Smart Cities that combines Internet of Things (IoT) with blockchain technology. We describe a system based on Hyperledger Fabric that provides safe and efficient data gathering, authentication, preservation, and smart contract execution. A continuous monitoring of water quality parameters, such as pH, temperature, turbidity, and dissolved oxygen, is achieved using the proposed IoT system. The collected data is stored on a secure blockchain ledger using Hyperledger Fabric, ensuring transparency, immutability, and security. Smart contracts are used to automate the water distribution process, enabling the system to efficiently allocate water resources based on demand and quality. Furthermore, the use of blockchain technology ensures that water quality data cannot be tampered with, providing a high degree of trust and accountability in the system. Overall, the proposed system represents a significant step towards a sustainable and secure future for water management in cities. This technology can revolutionize the way we manage and distribute water resources, ensuring safe and clean drinking water for future generations.
