ABSTRACT

Emergencies often disrupt communications systems and disrupt other rescue and recovery efforts. When the communication system of certain signaling nodes is attacked by emergencies, it can lead to a base station fault, and connection and communication will avoid the failure of the base station, then incorporated into the adjacent base stations, leading to the adjacent base station capacity surged, more than its maximum capacity, which causes the fails, the failure of dynamic transmission cascading failure can lead to communication systems. Based on the bidirectional transmission of a communication, the communication system has dual requirements of receiving and feedback, and traditional fault modeling of communication system is difficult to meet the dynamic failure of the communication system completely. Therefore, based on the wireless mesh network technology, this paper conducts a simulation analysis of the cascading failure process of communication systems. It can be found that the cascading failure propagation speed is faster when the key nodes are attacked than when the signal path is attacked.
