The Internet of Medical Things (IoMT) is a rapidly evolving research domain that connects medical devices, sensors, wearables, and healthcare systems through intelligent networks to improve patient monitoring, diagnosis, and treatment. Research papers in this field explore secure and efficient data collection, transmission, and analysis for real-time healthcare applications such as remote patient monitoring, chronic disease management, emergency response, and personalized medicine. Key focus areas include lightweight encryption, privacy-preserving data sharing, AI-driven analytics, edge/fog computing for low-latency decision-making, and blockchain-enabled trust management. Challenges such as interoperability across heterogeneous devices, scalability in large healthcare networks, cybersecurity threats, and compliance with regulations like HIPAA and GDPR are also widely studied. With the integration of 5G/6G, federated learning, and zero trust architectures, recent IoMT research emphasizes reliable, secure, and intelligent healthcare ecosystems that support proactive, patient-centered care.
