Abstract
In remote, mountainous, or snow-covered regions, mobile networks and GPS signals usually become unreliable, which creates major challenges for search and rescue (SAR) operations. To overcome the issue, this paper presents a compact, low-power, voice-activated wearable device that integrates LoRa communication with a TinyML-based keyword detection system. The proposed device enables individuals to send signals in areas where GPS coverage is unavailable. Using the Received Signal Strength Indicator (RSSI), the system applies trilateration techniques to get an approximate location of the user without having to rely on GPS. When someone says words like “Help” or “Bachao”, etc., the device quickly sends an emergency message using LoRa technology. This message includes the person’s location, either from GPS or by estimating it using the signal strength (RSSI) if GPS isn’t working. The rescue team, who have special LoRa receivers, can study the signal strength to guess how far and in which direction the person is. This makes it easier and faster for them to find the person, especially in mountainous or hard-to-reach areas, and increases the chances of saving lives.
