Abstract: Nowadays, the security system of the nation depending upon the enemy’s war and sothe security of the soldiers is considered as an important role in it.Concerning the safety of the soldiers, there are numerous tools to observe thehealth condition of the soldiers .The proposed system uses GPS to track thedirection of the soldier in the form of latitude and longitude values. So thatdirection can be found easily. The proposed system can be mounted on thesoldier’s body to track their health status and current location using GPS. Theseinformation will be transmitted to the control room through IoT. The proposedsystem comprise of tiny wearable physiological equipment’s, sensors,transmission modules. Hence, with the use of the proposed equipment, it ispossible to implement a low cost mechanism to protect the valuable human lifeon the battlefield. Designing of this system using GPS and GSM gives a wirelesssystem for tracking the location of the soldier and observing the heart beatrate and body temperature of the soldier.
