Abstract: MediShield IDS is an IoT-based smart health mon- itoring and security system designed to provide continuous, secure, and intelligent patient care in hospitals. The system includes a wearable smart health band that monitors vital signs like heart rate, body temperature, oxygen saturation (SpO), and patient movement in real time. The band uses biomedical sensors and an ESP32 microcontroller for efficient data collection and wireless communication. The collected health data is securely sent to a cloud-based platform or mobile app, allowing doctors and caregivers to monitor patient health remotely and respond quickly to critical situations. Besides health monitoring, the system provides indoor navigation and real-time patient tracking with Bluetooth Low Energy (BLE) beacons and motion analysis using an accelerometer. This feature helps elderly and disabled patients navigate hospital areas safely with turn-by-turn guidance through vibrations or display alerts on the wearable device. At the same time, healthcare staff can track patient locations via a web-based interface, improving emergency response, patient management, and operational effectiveness. To tackle growing cy- bersecurity issues in medical Wireless Sensor Networks (WSNs), MediShield IDS includes strong security measures like end-to-end data encryption, device authentication, and anomaly detection to block cyberattacks, data spoofing, and unauthorized access. By combining health monitoring, indoor navigation, real-time tracking, and intrusion detection into one wearable solution, the system improves patient safety, privacy, independence, and hos- pital efficiency. MediShield IDS offers a secure smart healthcare solution that meets the needs of modern digital hospitals.
