Delay- and Disruption-Tolerant Bluetooth MANET-Based Dual-Purpose Systems for Normal and Disaster Situations

The assurance network design principle makes systems work stably in both normal and disaster situations. We have been studying and developing assurance-based dual-purpose systems, which are available in both normal and disaster situations. Also we have developed a prototype of network applications for such systems. The prototype has two types of graphical user interface (GUI) for both situations. The GUI automatically switches to another type whenever each mobile terminal receives a special packet in disaster situations. We have unified such systems and their GUI so that users can understand how to use them even when GUI is automatically switched. To show feasibility of the dual-purpose normal and disaster situations system, we demonstrate behavior of the proposed system and scenarios for evaluation.
