Abstract

The rapid proliferation of mobile Internet of Things (IoT) devices has resulted in an exponential increase in data generation, storage, and sharing, which poses significant challenges related to security, privacy, integrity, and trustworthiness. Traditional centralized architectures for IoT data exchange are inherently vulnerable to single points of failure, unauthorized access, data tampering, and limitations in scalability. Blockchain technology, with its decentralized ledger structure, cryptographic integrity, and consensus mechanisms, provides a promising approach for enabling secure and reliable data sharing in mobile IoT networks. This paper presents a comprehensive analysis of blockchain-enabled secure data sharing frameworks, detailing critical architectural components such as smart contracts, lightweight consensus protocols, and cryptographic primitives. Furthermore, it evaluates performance and security benefits, including enhanced data integrity, accountability, and resilience against attacks. Finally, the paper identifies key challenges, including resource constraints, scalability issues, and privacy concerns, and outlines potential future research directions for integrating blockchain technology into dynamic mobile IoT environments.
