Abstract
So far, we have investigated a unified Wide area Disaster information Network (WDN) using Internet based on the combination of both the wired and wireless networks. In this paper, we introduce Resource Management System (RMS) for WDN to recover from system failure with serious damage when the disaster happened. The system configuration and architecture are described and their functions are precisely explained. The prototyped system based on our suggested WDN was built to demonstrate its functionality.
