Abstract

The swift urbanization is increasing the implementation of Internet of Things (IoT) technology to allow smart urban areas to gather, process, and analyze huge amounts of heterogeneous data. But the decentralized character of urban IoT ecosystems also comes with the essential issues of security, trust, transparency, interoperability and data governance. This paper presents a proposal of Blockchain-Based Secure Data Sharing Framework (BBS-dsf) that is aimed at dealing with these drawbacks and proposes the following concepts, decentralized consensus, immutable ledgers, and access control based on smart contracts. The framework combines edge computing architecture with lightweight blockchain protocols in an effort to provide scalability and still remain energy efficient. Using simulated tests, the proposed system will show enhancement of secure data exchange, latency, and resistance to single point of failure in comparison to traditional cloud-centric architecture. Practical challenges consist of overloading of constrained devices with calculations needed by IoT and complexity of integration across existing infrastructures and the potential possibilities of broad privacy risks with encryption. The future directions are to incorporate zero-knowledge proofs, artificial intelligence based on anomaly detection, cross-chain interoperability and green blockchain mechanism to enhance the efficiency, privacy, and flexibility to the next-generation smart cities.
