网络化作战中通信网络相继故障规模的降低方法研究

Study of reducing size of cascading failures in communication network of network centric warfare

通过研究网络化作战中通信网络的相继故障现象,找到其规模的降低方法。着眼于网络化作战中通信网络相继故障的主要影响因素,从充分利用网络资源的观点出发,采用基于节点剩余容量的负载重分策略,建立了一个网络化作战中通信网络的相继故障模型,并进行了仿真实验研究。结果表明,与基于节点度的负载重分策略相比,基于节点剩余容量的负载重分策略能降低网络相继故障的规模约10%;同时研究还发现当网络中节点的初始负载不同时,初始负载较小的网络首先进入相继故障状态且相继故障规模较大;另外研究还发现了当网络化作战中的通信网络具有社团结构时,相继故障的规模要减小约30%～50%,并且网络能够承担更多的负载。

By studying the cascading failures in communication network of network centric warfare,it found some methods of reducing the size of cascading failures. Aimed at the main factors which could affect the process of cascading failures,presented a model of cascading failures in communication network of network centric warfare and some simulations in follows. In the model,it adopted a new strategy of redistribution,and found it could reduce the size of cascading failures about 10%. When the network had smaller initial loads than other networks,it firstly entered the process of cascading failures,and it had a larger size of cascading failures. Otherwise it studied the scale-free network with community structure in cascading failures and found that this structure made the size of cascading failures reduced about 30% ～ 50% ,and this network could take more loads.
