Abstract
Recent advances in disaster prediction and detection technologies and Information and communications technology (ICT) support infrastructures have enabled the generation and reliable deliveries of machine-readable early disaster alerts over all communication pathways. Relatively, ubiquitous smart devices, systems and applications that can receive, authenticate and process standard-conforming disaster alert messages and respond by taking appropriate actions to help us to be better prepared for nature disasters is the next step for the advance of disaster management technologies. This thesis focuses on the design and prototypes of such smart devices/systems/applications called iGaDs (intelligent Guards against Disasters). iGaDs are designed to process and respond to disaster alert messages that are in a standard XML format, generated authorized emergency alert services. iGaDs can help people to be better prepared when disasters happen thus reduce the danger in emergency.
