英文摘要：

In allusion to the characteristic of dynamic WMN network,this paper puts forward a new estimate index of network invulnerability and sets up a incidence matrix to depict the connectivity of the network nodes in a dynamic network model.Then,this paper brings forward a determinant arithmetic of the network connectivity and a calculate method,which based on the Breadth First Search.This paper also simulates the damage situation of the dynamic WMN network through random trials,and quantitatively calculates the ratio of the network invulnerability,which related to time.As a result,it validates the high invulnerability of the dynamic WMN network.
