A New Ballooned Wireless Mesh Network System for Disaster Use

In this paper, a ballooned wireless mesh network is proposed to promptly insure communication means to grasp the information with disaster area, residentpsilas safety and relief goods on the occurrence of disaster. By combining multiple ballooned wireless network nodes, a large mesh network is organized in the sky on the disaster area and can cover shelters or interrupted communication area as urgent communication means. The system configuration and its function are described. A prototype system is constructed to evaluate its function and performance through several disaster applications such as WIide area Disaster Information and Sharing System(WIDIS), VoIP, and omni-directional video surveillance system.
