An analysis of the invulnerability for communication networks base on Cascading failure model

In order to establish a high-quality cascading failure model of communication network, the influence of load parameters, capacity parameters and network evolution step size on the invulnerability of network cascading is analyzed by numerical simulation under the load capacity nonlinear model and load local priority redistribution principle. A communication network model based on cascading failure is proposed. The experimental results show that each parameter has an optimal value under the standardized failure node number measure and the objective function measure considering performance and cost. Under the condition of fixed load parameters, the optimal combination of capacity parameters is obtained, which makes the network have the strongest cascading invulnerability, which has certain reference value for the design of cascading failure model of actual combat network.
