During the COVID-19 pandemic, there has been a significant increase in the use of internet resources for accessing medical care, resulting in the development and advancement of the Internet of Medical Things (IoMT). This technology utilizes a range of medical equipment and testing software to broadcast patient results over the internet, hence enabling the provision of remote healthcare services. Nevertheless, the preservation of privacy and security in the realm of online communication continues to provide a significant and pressing obstacle. Blockchain technology has shown the potential to mitigate security apprehensions across several sectors, such as the healthcare industry. Recent advancements in research have included intelligent agents in patient monitoring systems by integrating blockchain technology. However, the conventional network configuration of the agent and blockchain introduces a level of complexity. In order to address this disparity, we present a proposed architectural framework that combines software defined networking (SDN) with Blockchain technology. This framework is specially tailored for the purpose of facilitating remote patient monitoring systems within the context of a 5G environment. The architectural design contains a patient-centric agent (PCA) inside the SDN control plane for the purpose of managing user data on behalf of the patients. The appropriate handling of patient data is ensured by the PCA via the provision of essential instructions to the forwarding devices. The suggested model is assessed using hyperledger fabric on docker-engine, and its performance is compared to that of current models in fifth generation (5G) networks. The performance of our suggested model surpasses current methodologies, as shown by our extensive study including factors such as throughput, dependability, communication overhead, and packet error rate.
在 COVID-19 大流行期间，人们对互联网医疗资源的使用显著增加，这促进了医疗物联网（IoMT）的发展和进步。该技术利用各种医疗设备和测试软件通过互联网广播患者结果，从而能够提供远程医疗服务。然而，在在线通信领域，隐私和安全的保护仍然是一个重大且紧迫的障碍。区块链技术已显示出在多个领域（如医疗保健行业）缓解安全问题的潜力。最近的研究进展包括通过将区块链技术集成到患者监测系统中来实现智能代理。然而，代理和区块链的传统网络配置引入了一定程度的复杂性。为了解决这一差异，我们提出了一个结合软件定义网络（SDN）和区块链技术的建议架构框架。该框架是专门为在 5G 环境中促进远程患者监测系统而设计的。该架构设计在 SDN 控制平面内包含一个以患者为中心的代理（PCA），用于代表患者管理用户数据。PCA 通过向转发设备提供必要的指令来确保对患者数据的妥善处理。该建议模型在 Docker-Engine 上的 Hyperledger Fabric 上进行了评估，并与 5G 网络中的现有模型进行了性能比较。我们的广泛研究表明，我们提出的模型的性能优于现有方法，包括吞吐量、可靠性、通信开销和数据包错误率等因素。
