Industrial Internet of Water Things architecture for data standarization based on blockchain and digital twin technology☆

Abstract

The Industrial Internet of Water Things (IIoWT) has recently emerged as a leading architecture for efficient water distribution in smart cities. Its primary purpose is to ensure high-quality drinking water for various institutions and households. However, existing IIoWT architecture has many challenges. One of the paramount challenges in achieving data standardization and data fusion across multiple monitoring institutions responsible for assessing water quality and quantity. Additionally, ensuring data security and interoperability among the sensors and nodes within the IIoWT architecture remains a critical concern. This paper introduces the Industrial Internet of Water Things System for Data Standardization based on Blockchain and Digital Twin Technology. The main objective of this study is to design a new IIoWT architecture where data standardization, interoperability, and data security among different water institutions must be met. We devise the digital twin-enabled cross-platform environment using the Message Queuing Telemetry Transport (MQTT) protocol to achieve seamless interoperability in heterogeneous computing. In water management, we encounter different types of data from various sensors. Therefore, we propose a CNN-LSTM and blockchain data transactional (BCDT) scheme for processing valid data across different nodes. Through simulation results, we demonstrate that the proposed IIoWT architecture significantly reduces processing time while improving the accuracy of data standardization within the water distribution management system. Overall, this paper presents a comprehensive approach to tackle the challenges of data standardization and security in the IIoWT architecture. Based on Blockchain and Digital Twin Technology, the proposed system offers a promising solution for efficient water management in smart cities, ensuring users' reliable delivery of high-quality drinking water.
