Summary
First responders can now communicate reliably after disasters using the R-RDSP system. This wireless ad hoc network ensures rapid, infrastructure-free communication for post-disaster management.
Area of Science:
- Computer Science
- Network Engineering
- Disaster Management
Background:
- Cellular communication networks are frequently impaired after natural disasters or conflicts.
- Effective communication is critical for first responders coordinating rescue efforts and informing survivors.
Purpose of the Study:
- To develop a reliable, rapidly deployable wireless ad hoc system for post-disaster communication.
- To improve communication efficiency and reliability in infrastructure-compromised environments.
Main Methods:
- Developed the R-RDSP system using Data Distribution Service (DDS) middleware (RTI-DDS).
- Implemented a three-module architecture (client, relay, server) for device-to-device communication.
- Utilized ad hoc networking for infrastructure-independent connectivity.
Main Results:
- R-RDSP achieved a 14.5% improvement in end-to-end delay and a 20.24% improvement in round-trip delay over the RDSP scheme.
- Demonstrated robust performance in challenging network conditions.
- Ensured reliable message distribution for critical post-disaster information.
Conclusions:
- The R-RDSP system offers a viable solution for maintaining communication in post-disaster scenarios.
- The ad hoc network architecture provides essential connectivity without relying on damaged infrastructure.
- DDS middleware ensures reliable and efficient data distribution for coordinated emergency response.

39
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...

Electronic Distance Measuring Instruments (EDMs) are essential tools in modern surveying, offering precise distance measurements by emitting electromagnetic signals and calculating the time required for these signals to travel to a target and return. Two primary types of signals are used in EDMs — light waves and microwaves — each suited to specific environmental and distance requirements. Light-wave-based EDMs utilize either infrared or laser light, providing high accuracy over short...

Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...
