Revolutionizing Remote Healthcare: A Synergistic Approach with Blockchain, SDN, and 5G in IoMT

The COVID-19 pandemic has catalyzed a surge in internet-based healthcare services, driving the evolution of the Internet of Medical Things (IoMT). This transformative technology utilizes medical equipment and testing software to enable remote healthcare services by broadcasting patient results over the internet. However, the crucial challenge of ensuring privacy and security in online medical communication persists. Blockchain technology emerges as a promising solution, showcased in a proposed architectural framework combining Software Defined Networking (SDN) with Blockchain. Tailored for 5G environments, this framework introduces a patient-centric agent within the SDN control plane, managing user data securely and outperforming existing 5G models in factors like throughput and dependability.

In parallel, the article emphasizes the pivotal role of IoT in supporting online medical services. The IoMT, interconnecting medical devices and software globally, serves as the foundation for remote patient monitoring systems. Despite IoMT's potential during contagious diseases like COVID-19, privacy concerns hinder transparent healthcare systems. Blockchain's integration with 5G networks presents a solution by providing immutable device authentication records, enabling network segmentation for fair compensation, and ensuring decentralized and secure 5G ecosystems. The proposed model addresses challenges faced by traditional eHealth systems, emphasizing the significance of patient privacy in an interconnected healthcare landscape.
