Blockchain-enhanced sensing as a service for smart supply chains: A decentralized IoT framework

Utilizing the vast amounts of data acquired by sensor networks set up in various businesses is the foundation of smart supply chain services. When it comes to exchanging data, Sensing as a Service (S2aaS) is an intriguing pattern of IoT business models. Data security, performance, privacy, and single point of failure are just a few of the reasons why the present centralized Internet of Things (IoT) S2aaS models aren’t cut out for IoT large data sharing. We present a decentralized framework for IoT S2aaS for smart supply chains that is based on blockchain technology. Without the need for intermediaries, this framework may ensure that data consumers can safely communicate data with data owners of IoT solutions while retaining full ownership of their data. Researchers lay out the framework’s layered architecture and system model, from which derive a specific plan for implementing IoT S2aaS through the usage of smart contracts. We put an Ethereum-based software prototype into action. The outcomes of the experiments prove that our solution is both valid and effective.
