In this paper, we propose a location-based real-time safety system to contribute to the safety of hikers in mountainous areas.Based on an internet-of-things (IoT), which considers the signal shadowing in the mountainous regions, we developed a method to detect safety events by analyzing the hikers' location stream in real time.For this purpose, we define event types that can be detected using the hikers' location stream.In addition, we propose a method to continuously process queries by indexing the hikers' locations on the grid at the mountainous region to achieve an effective event detection.It is also designed to detect events based on a big data stream processing platform that can handle scalable high-speed largecapacity location streams.Using a structured query language (SQL) database management system, we verify the proposed event detection algorithm.
