一种恶意节点攻击的无线传感器网络入侵检测方法

摘要

无线传感器节点通常被随机部署在没有基础网络设施的场所,当传感器节点位置暴露在恶意攻击环境时,攻击者会攻击网络覆盖漏洞,节点易受到未知攻击从而导致定位错误,无线传感器网络很难在没有人工参与的情况下安全运行.针对此问题,设计了一种基于无线传感器网络节点的入侵检测算法.该算法能解决无法识别的未知攻击问题,通过聚类技术检测攻击产生的异常值,并在理论上证明了该算法的正确性.通过测试和实验手段,验证了该算法在保护传感器网络的前提下,完成了对未知攻击的检测、修复和定位.%Wireless sensor nodes are usually random deployment in the absence of infrastructure network.When the sensor node position exposed to malicious attacks environment,the attacker will attack the network coverage holes,and nodes are vulnerable to unknown attacks leading to positioning error.Wireless sensor networks is difficult to operate safely in no case of human involvement.To solve this problem,an intrusion detection algorithm based on wireless sensor network node is designed,which can solve the problem of unrecognized unknown attacks.The outliers generated by attacks are detected through clustering techniques,and the correctness of the algorithm is proved theoretically.Test and experiment means that the algorithm on the premise of protecting the sensor network completes the unknown attack detection,repair and positioning.
