Real-Time Soldier Health Monitoring and Position Tracking Using LoRa-Based IoT System

Abstract

Military capability is fundamentally determined by the effectiveness of its land, air, and naval forces. To enhance situational awareness and ensure the safety of personnel in real-time, this research proposes a compact, wearable soldier monitoring system. The proposed device, which can be easily mounted on a soldier gear, facilitates real-time tracking of physiological parameters and geolocation data. It integrates sensors to monitor heart rate, pulse, body temperature, and motion — key indicators for assessing a soldier's health and fatigue levels during active combat or field operations. The system leverages Long Range (LoRa) communication technology, enabling low-power, long-distance data transmission between the soldier and a central monitoring unit. LoRa's capability to maintain connectivity in remote and obstructed environments makes it highly suitable for military applications. This integration enhances command center awareness, enabling timely medical intervention and operational decisions. The proposed system not only improves troop survivability but also contributes to mission efficiency through robust, energy-efficient design. The project achieved an accuracy exceeding 97%, indicating high reliability and performance.
