摘要
针对实际航空网络机场节点对负载具备一定冗余,文章提出一种考虑节点容量的负载分配方法,首先,定义网络的节点过载系数和容量模型,对航空网络的级联失效过程进行建模;其次,定义正常节点、过载节点和失效节点三种节点负载状态,根据节点不同负载状态选择不同的负载分配方式。通过仿真分析航空网络在三种攻击方式下网络最大连通子图比例的下降情况,研究发现,随着攻击节点的增多,网络最大连通子图的比例逐渐降低,但与传统负载分配方法相比,基于临界容量的负载重分方法可以有效减缓网络最大连通子图比例的下降趋势,提高网络在级联失效时的稳定性。
Aiming at the actual aviation network airport nodes have a certain redundancy to the load,a load allocation method considering the node capacity is proposed,firstly,the node overload coefficient and capacity model of the network are defined,the cascade failure process of the aviation network is modeled,and three node load states of the normal node,overloaded node,and failed node are defined,and different load allocation methods are selected according to the different load states of the nodes.Through simulation to analyze the decline of the proportion of the maximum connected subgraph of the network in the aviation network under the three attack methods,it is found that the proportion of the maximum connected subgraph of the network gradually decreases with the increase of the attacking nodes,but compared with the traditional load allocation method,the load re-distribution method based on the critical capacity can effectively slow down the decreasing trend of the proportion of the maximum connected subgraph of the network,and improve the stability of the network in the event of cascade failure.
