基于独立监督网络的选择性转发攻击检测

Selective Forwarding Attack Detection Based on Independent Monitoring Network

针对无线传感器网络中恶意节点的选择性转发攻击检测,提出了一种采用独立监督网络的选择性转发攻击检测方案。通过设置独立的监督网络,保护监督节点的位置信息,使监督节点仅在安全网络环境下向基站提供簇头转发信息。基站通过监督节点日志对传输过程中各簇头节点的数据转发情况和信道状态进行检测,提高对选择性转发攻击的检测,同时降低由信道丢包引起的节点误检。实验表明,IMN-SF方案可以检测网络中发动选择性转发攻击的节点。与相似算法相比,该方案在提升检测率的同时降低了误检率,并且增强节点负载均衡,延长了网络生命周期。

An Independent Monitoring Network for Selective Forwarding Attack Detection(IMN-SF)scheme is proposed to detect selective forwarding attack of malicious nodes in wireless sensor networks.The independent monitoring network is set up to protect the location information of the monitoring node,which can provide cluster head forwarding information to the base station in a secure network environment.The base station detects the data forwarding of each cluster head node and channel status in the transmission process through the monitoring node log,so as to improve the detection of selective forwarding attacks and reduce false detection caused by channel packet loss.Experiments show that the IMN-SF scheme can detect nodes that initiate selective forwarding attacks in the network.Compared with similar algorithms,the scheme improves the detection rate,reduces the false detection rate,enhances the load balancing of nodes,and prolongs the network life cycle.
