A review on smart wearable devices for soldier safety during battlefield using WSN technology

In current years, warfare plays a vital role in the nation's security. Army soldiers play an important and major role in combats as well as in providing peace to the nation. Soldiers provide security to the nation; it is important to safeguard their lives with minimum social responsibilities as they are risking their lives in protecting us. To improve their security, advanced devices are equipped with the soldiers to view their status of the health and as well as the live location of the soldier and a lot more. In this paper, it is focused to provide the safety to the soldiers in all aspects by giving the smart wearable's using WSN (Wireless Sensor Network) technology. Smart wearable like a smart vest, smart helmet, and the smart strap is equipped with BSN (Body Sensor Network) to determine the various psychological parameters and mental state of the solider. These smart wearable devices are capable of monitoring the health of soldier and ability to track the live location in real-time, by this if a soldier gets injured in the battlefield within no time the information transmitted to the control unit using LoRaWAN (Long Range Wide Area Networking) and to the nearby soldiers using Zigbee module by forming a Mobile Ad-hoc Network (MANET), so that the control unit can take any necessary actions for saving the life of the soldier.
