【摘要】 针对传统的节点损伤定位一直存在精度低的问题,提出基于自适应波束形成的关联节点损伤定位器设计方法。建立网络入侵中的关联节点拓扑结构模型,提取损伤节点输出信息的异常频谱特征,采用自适应波束形成方法进行关联节点损伤部位的物理特征参量估计,实现节点准确定位。仿真结果表明,采用该方法进行关联节点损伤定位的精度较高,收敛性较好。更多还原

【Abstract】 Aiming at the problem of low accuracy in traditional node damage localization,a design method of association node damage locator based on self-adaptive beam-forming is proposed. A topology model is constructed for association nodes in network intrusion,the abnormal spectrum characteristics of damaged nodes output information are extracted,and the self-adaptive beam-forming method is adopted to estimate physical characteristic parameters of the damaged parts of association nodes,to achieve accurate node localization. The simulation results show that the proposed method has high accuracy and good convergence for association node damage localization.更多还原
