Abstract: In this paper, we have implemented a low-cost embedded system developed for soldier's assistance. The system consists of interconnected body sensor networks for real-time health monitoring and environmental analysis of the soldier and the communication is done with the base station using long range (LoRa) module. The data collected from each sensor is processed using a robust and steady algorithm to decide the health and environmental conditions of the soldier. The health status is further classified into healthy, wounded or dead. All the collected data along with the obtained results about the soldier's health condition are then encrypted and transmitted to the base station securely. The system uses only 3.2 Wh energy making it energy efficient to extend the operational time. The information can be transmitted up to 700 metres at 2400 baud rate and could be increased further by reducing the baud rate.
