Disaster information network is very important for people in many countries, particularly in Japan because there are many serious disasters have occurred annually. So far we have developed a disaster information network based on wireless LANs because of their mobility, portability and easy installation. In order to improve the connectivity and to attain the longer communication distance, we introduce a dynamic network configuration based cognitive Radio LANs. Currently available wireless LANs such as IEEE802.11b,g,j,n, IEEE802.16, cellular network, personal wireless network are combined with a mobile router and loaded on a car to quickly build a emergency temporal disaster information network when the usual communication network infrastructure was seriously damaged. In this paper, we designed and implemented a wireless mobile network using currently available different wireless network and pc based routers. Its network architecture and network protocol are specified to realize high performance connectivity and throughput. A simple prototype system is constructed to evaluate the functional and performance. As a result, we could verify the feasibility of effective and flexible disaster information network.
