Summary
This study introduces a novel distributed multi-tier emergency alerting system for smart cities. It enhances real-time event detection and alarm generation using multiple sensors and GPS data, improving urban safety.
Area of Science:
- Computer Science
- Electrical Engineering
- Urban Planning
Background:
- The Internet of Things (IoT) has enabled numerous sensor-based monitoring applications for environmental perception and emergency detection.
- Existing IoT emergency systems for smart cities are limited by single-variable monitoring and high computational demands on sensor nodes.
Purpose of the Study:
- To propose a distributed, multi-tier emergency alerting system for smart cities.
- To address the limitations of current IoT-based emergency systems by incorporating multiple data inputs and reducing computational burden.
Main Methods:
- Developed a distributed multi-tier system with sensor-based event detection units.
- Integrated configurable scalar sensors and GPS data for real-time, georeferenced event information.
- Computed emergency alarms based on detected events, area risk levels, and temporal data.
- Implemented the system on open-source electronic platforms and created a real-time map visualization application.
Main Results:
- The system provides modular and flexible perceptions of critical events tailored to smart city scenarios.
- Demonstrated a feasible and useful application as a supporting service for smart cities.
- Achieved real-time georeferenced information and dynamic display of emergency alarms on a map.
Conclusions:
- The proposed system offers an innovative approach to enhance smart city emergency preparedness.
- It supports the development of adaptive, IoT-based emergency-aware applications.
- This implementation can yield valuable results for improving urban safety and response.

Applications of GIS: Disaster Management and Emergency Response
391
Geographic Information System (GIS) technology is essential for risk identification, action prioritization, and resource optimization in critical situations like flooding and earthquakes. By integrating spatial and demographic data, GIS provides a comprehensive framework for emergency response.GIS integrates data layers, like rainfall intensity, topography, elevation profiles, and river levels, to model high-risk flood zones. These layers assess areas susceptible to flooding based on their...
