Abstract: Significant safety concerns are associated with trekking in distant or difficult areas, as people are frequently at risk of getting lost or running into emergencies. This article suggests integrating Fog IoT technology into hiking GPS systems to provide real-time tracking and safety monitoring for trekkers in order to successfully address these difficulties. The approach entails the thoughtful placement of edge sensors and gateways along the hiking route in addition to the strategic deployment of IoT devices with GPS sensors on both trekkers and equipment. Strategically placed at vital junctures, fog nodes are essential for locally processing GPS data, allowing for quick analysis of planned route deviations and possible crises. By taking a decentralized method, latency is drastically decreased and bandwidth is preserved, guaranteeing effective data transfer to a central base station.

When possible problems are found in trekker GPS data, the base station acts as a complete command centre, making it easier to coordinate rescue efforts in reaction to alerts. To further improve overall safety and rescue effectiveness, the system keeps a library of past GPS data for post-event analysis, route optimization, and incident assessment. Even in the most distant and difficult environments, this integrated method significantly increases outdoor adventure security by streamlining resource utilization, strengthening safety procedures, and utilizing cutting-edge technology.
