Design and implementation of dual-purpose normal and disaster situations systems based on delay and disruption tolerant Bluetooth MANETs

We have been studying and developing dual-purpose systems, which are available in both normal and disaster situations, and which are based on the assurance network design principle. The assurance network design principle makes the dual-purpose systems work stably 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 validate feasibility of the dual-purpose normal and disaster situations system, we show experimental results on dissemination of evaluation information and automatical switching of GUIs.
