        abstract = {The rapid advancement of the Internet of Medical Things (IoMT) has significantly transformed modern healthcare by enabling continuous patient monitoring, remote diagnosis, intelligent disease management, and real-time communication among medical devices, healthcare professionals, and patients. The increasing deployment of wearable sensors, implantable medical devices, smart diagnostic equipment, and cloud-connected healthcare applications has generated an unprecedented volume of sensitive medical information that requires secure transmission and storage. However, conventional healthcare communication systems primarily rely on centralized cloud infrastructures, making them vulnerable to cyberattacks, unauthorized data access, single points of failure, insider threats, and privacy breaches. These security concerns limit the adoption of IoMT in critical healthcare environments where patient confidentiality and data integrity are essential.
Blockchain technology has emerged as a promising decentralized solution for improving trust, transparency, and security in healthcare communication. By combining distributed ledger technology with smart contracts, healthcare organizations can automate patient consent management, authentication, authorization, and secure medical data sharing without relying on a centralized authority. Nevertheless, existing blockchain-based IoMT solutions continue to face challenges related to scalability, communication latency, metadata leakage, computational overhead, interoperability among heterogeneous medical devices, and smart contract vulnerabilities.},
