The wireless ad hoc network is expected to be used as an alternative of the existing mobile communication network to make users communicate securely in a so-called emergency when a large-scale disaster occurs. In this paper, we propose a Real City model which is more practical as a user terminal movement model in the emergency case. Then we analyze the performance of wireless ad hoc networks in the Real City model by using the network simulator. From the simulation results, it is clarified that changing die routing protocol attribute value and increasing the number of mobile terminals that contributes to the communication route formation are necessary to improve the ad hoc network performance.
