An Automated Smart Contract-Based Architecture for IoT Device Recruitment and Service Provisioning

Abstract

In recent years, the adoption of the Internet of Things (IoT) has spread rapidly in various fields, enhancing technology and facilitating human life. To improve operational efficiency, user experience, and predictive maintenance of IoT applications, dynamic device recruitment and service provisioning are adopted instead of manual and fixed architectures. This raises challenges in adaptability, trust, and security, especially in heterogeneous environments such as smart cities. This paper utilizes blockchain and smart contracts to automate the process of IoT device recruitment and service provisioning. It proposes a decentralized architecture including a trust authority component for authentication, a smart contract generation component, and a negotiation component for dynamic contract refinement. This ensures a seamless and secure communication between the service provider and requester without reliance on third-party and manual intervention. The architecture components are presented in detail, and the full process from registration and authorization to dynamic contract generation and negotiation is then explained. It shows how manual intervention is reduced while ensuring trust and adaptability. Future work includes model formalization, prototype implementation, and performance evaluation.
