Abstract	Wireless LANs are very useful as disaster information networks because of their mobility, portability and easy installation. However, in the actual disaster case, electric power line is also damaged and those wireless LANs cannot be functioned. In this paper, we introduce a power saving cognitive wireless LANs for disaster use with combination of solar panel, wind turbine and battery, so that, the autonomous wireless network can be established and provide normal network functionality even through the other wired electric power and network are seriously damaged. Furthermore, by combining with multiple LANs with different transmission characteristics and selectively switching those, suitable communication environment can be provided even though the communication environment has been changed. Using combination of fixed and mobile cognitive networks, a large disaster communication network is organized. In this paper, we designed a wireless mobile network with currently available different wireless LANs and constructed a prototype system to evaluate the functional and performance.
