Convergence of Blockchain and Internet of Things Using Hyperledger Fabric

Abstract

Internet of Things (IoT) is becoming increasingly significant and has the ability to benefit society. It offers several benefits such as interconnectivity, ubiquity, data generation, automation, real time monitoring, predictive analysis and resource optimization. It can be used in a variety of settings, such as buildings, businesses, healthcare, agriculture, and transportation, among others. Its widespread use makes it a flexible and potent technology. Due to its potential to revolutionize healthcare delivery, improve patient outcomes, increase operational efficiency, and lower costs, the IOT is crucial for the healthcare industry. While IoT-based healthcare solutions have numerous advantages, there are also a number of problems and difficulties that must be properly resolved in order for them to be successfully implemented and used. The primary concern is security and privacy. Integration of blockchain and IOT can be highly useful in various healthcare industry by addressing critical issues related to security, trust, data integrity, and automation. The primary objective of this study is to demonstrate how IOT based healthcare sensors can communicate with blockchain networks to make the whole healthcare eco-system highly secure and efficient. Initially, effective blockchain framework and RPM (Remote Patient Monitoring) sensors were identified. This study deployed Hyperledger fabric framework to implement the RPM system. Thereafter, two experiments were conducted and it is found that there was no packet loss when RPM transactions were sent to blockchain network at the speed of 2 transactions per minutes but the system encounter with packet loss at 5 transactions per minute.
