摘要
为有效分析节点失效波及反应导致航空自组网稳定性的变化,提出一种航空自组织(AANET)节点失效分析方法。首先,根据AANET特性建立业务-实体非对称依赖网络模型;其次,设计改进失效流量重分配算法,获取受影响节点数据集;最后,根据节点权值计算在AANET中的波及影响值,并对波及影响程度定级。实验结果表明所提方法在AANET节点失效波及影响分析方面具有更好的准确性。
To analyze the stability changes of aeronautical ad hoc network(AANET)caused by node failure affecting reaction effectively,an AANET node failure analysis method was proposed.Firstly,the model of business-entity asymmetric dependent network was established based on the characteristics of AANET.Secondly,an improved failure traffic redistribution algorithm was designed to obtain the affected node set.Finally,the AANET affecting impact value was calculated according to the node weight,then the affecting impact degree was determined.The experimental results show that the proposed method has better accuracy in the failure affecting impact analysis of AANET.
