Cognitive wireless network consisted of multiple different types of wireless interface is one of efficient wireless transmission methods for Disaster Information network, because it solves single wireless network problems like characteristics of wireless frequency or congestion form the use of same radio frequency. However, even if disaster information network consisted of cognitive wireless network, some of wireless node might be broken after severe disaster is happened. Therefore, it is necessary to consider about additional functions which the system never die. In this paper, the authors introduce satellite system for optimal transmission control method in cognitive wireless network in order to consider with severe disaster.
