Abstract :

Modern Military Operations Often Take Place In Remote Or Hostile Environments Where Reliable Communication Infrastructure Is Limited Or Completely Absent. Ensuring The Safety And Continuous Monitoring Of Soldiers Under Such Conditions Is A Critical Challenge. This Work Presents A Smart, IoTbased Soldier Monitoring System That Utilizes Long-range Communication To Track Both Physiological And Environmental Parameters In Real Time. The Proposed System Integrates Multiple Sensors, Including A DHT11 Module To Measure Surrounding Temperature And Humidity, And An SpO₂ Sensor To Monitor Blood Oxygen Levels And Heart Rate. In Addition, A MEMS-based Accelerometer Is Incorporated To Detect Sudden Movements Or Falls, Which May Indicate Injury Or Distress. To Provide Accurate Positioning, A GPS Module Is Used To Capture The Real-time Geographical Location Of The Soldier. A Dedicated Panic Button Is Also Included, Allowing The Soldier To Manually Trigger An Emergency Alert Whenever Immediate Assistance Is Required. All Sensor Data Is Collected And Processed By A Microcontroller Unit At The Transmitting End And Then Sent Wirelessly Over A Low-power, Long-range Communication Network To A Receiving Station. At The Base Unit, The Transmitted Information Is Decoded And Displayed For Monitoring Purposes. The System Is Designed With Energy Efficiency In Mind, Ensuring Reliable Operation During Extended Field Missions. By Enabling Continuous Health Tracking And Location Monitoring Without Dependence On Cellular Or Wi-Fi Networks, The Proposed Solution Significantly Enhances Situational Awareness And Supports Timely Decision-making, Ultimately Improving Soldier Safety And Operational Effectiveness.
