According to the damage of access points under emergency condition, emergency communication system with limited frequency resource should be employed to establish communication link temperately and a frequency reuse scheme is needed to increase system reliability and ability in real-time environment. A mobile tree-mesh backbone network structure and a distributed frequency assignment scheme, which is based on local power detection, are proposed in the paper to realize frequency reuse. A random walk strategy is used to simulate mobile node which follows a random distribution in a given area.
