摘要: 干扰攻击会导致节点状态跳转规律发生变化。为此,在节点状态跳转统计分析的基础上,提出一种改进的干扰检测算法。在学习阶段,通过学习无干扰和有干扰场景下的样本,获取节点各状态时间占比的干扰检测判决门限和干扰类型判决门限。在检测阶段,对节点的各状态时间占比与对应的判决门限进行比较,检测干扰攻击并判断其类型。采用加权检测置信度方法进一步提高检测正确率并降低误报率。在NS3上的仿真结果表明,该算法的误报率较低,能够准确检测到典型的按需和持续干扰攻击。

Abstract: Jamming attacks may cause the change of node state transition rule.Based on the statistical analysis of node state transition,this paper puts forward an improved jamming detection method.At the learning phase,the jamming detection judgment thresholds and jamming type judgment thresholds of the proportion of node state time are extracted through learning from samples collected from jamming and jamming-free scenarios.At the detection phase,these corresponding decision thresholds are compared with the proportion of node state time to detect the jamming attacks and determine the jamming types.The method of weighted detection confidence is proposed to further improve the detection rate and reduce the false alarm rate.Simulation results on NS3 validate that the proposed algorithm can accurately detect the typical on-demand and continuous jamming attacks with low false alarm rate.

Key words: Ad hoc network, jamming detection, proportion of state time, state transition, weighted detection confidence
