With the advances in an information and communications society, information networking has become an infrastructural service that is as important as the supply of electricity, gas and water.
Given this context, this study seek to design an effective anti-disaster information network and also develop the application technologies exploiting the network effectively. To investigate how such a network could be deployed, we constructed an experimental network in a laboratory and set up an environment to test various applications. To support visual applications, we realized two video functions of (a) real-time disaster video distribution and (b) multimedia disaster-information acquisition. What you just saw was, in my opinion, an abuse of the Disaster Prevention Radio system set up by the Japan government’s Fire and Disaster Management Agency (FDMA). With the goal of relaying accurate information related to disasters in a speedy manner, there are public announcement radio systems (loudspeakers) set in elementary and junior high schools and public parks. I’m fine with having such a network of loudspeakers dotted across the landscape if they are used for their intended purpose, that is to relay disaster information. I am a publisher of THE EAST; the only English newspaper, which is mainly focused on the East Asian information (at the beginning of every month, more than 12,000 free copies are distributed throughout the London area, particularly, where East Asian Networks are established). Surely Nick, this is just a way of making sure the system works properly should a disaster hit.

The network system is designed such that it could be used to collect, accumulate, analyze, display and dispatch disasterrelating information for disaster prevention at usual times, and that it could serve as a communication means for disaster relief in the event facilities were damaged or traffic congestion occurred in response to an emergency. From a terminal with a web browser, users can post text-based local status information on the bulletin board with position information and view the latest information through the browser. 4 is capable of sending video, voice, data logger, and other data to the server using the mail function of a mobile phone or a PC-like terminal in a way that the server can automatically extract data files and present the information in a way that can be accessed on a browser by users.
The main concerns in information networks to cope with a disaster have conventionally been enhancement of network reliability, being able to secure critical communications and to restore services quickly. Further work on the technology required for establishing an effective information network for disaster mitigation is currently being undertaken, with particular attention on the implementation of the information bulletin board, real-time disaster video distribution, and multimedia disaster-information acquisition functions. The disaster radio systems built by the national and local governments are based on the experience gained in past disasters. While public networks have been designed with some disaster mitigation measures in mind, the damage to facilities and traffic congestion that a disaster would cause may render these networks less effective for dealing with the specific applications such as protection of cultural assets. To implement the network we investigate the network technologies using satellite communications, wireless LAN and ad-hoc networks as well as the network-associated technologies for location estimation capable of operating seamlessly indoors and outdoors. Users of mobile terminals can input text-based information on a simple input screen with position information.

The purpose of the radio systems is to secure a means to collect and transmit disaster information in the times of emergency. The need has therefore arisen for a unique approach to the design and implementation of anti-disaster networks. The networks can collect and distribute information efficiently without being adversely affected by structural damage or traffic congestion. 3 distributes video data captured at the scene of the disaster in real time using a Windows terminal and a web camera to a web site. The primary difficulty associated with anti-disaster networks is that they must be regularly maintained and managed so that they will capable of executing the necessary tasks with a high degree of reliability in the event of a disaster whose location and timing cannot be predicted.
