Abstract: For the limitations of the mathematical model when reflecting cascading failures, based on the principles of complex networks and graph theory, this paper models for wireless communications networks, and studies the network fault propagation as well. According to the complexity of the network scale model, a line graph model composed by network nodes and communication channel is formulated. It studies the cascading failure in wireless communication network in the aspects of network error level, node fault tolerance level, the initial number of the failed node and so on. Simulation results show that the line graph model can reflect more intuitive network characteristics, and fault parameters can affect the spread of cascading failures in the communication network.

Key words: wireless communication network, complex network, topology model, cascading failure
