摘　　要：为了确保无线传感器网络中的源节点位置不被恶意泄露,保障其安全性能与网络能耗均衡,提出一种无线传感器网络源节点隐私位置信息保护方法。以熊猫-猎人位置隐私保护模型为基础,构建一个六元组系统防御攻击模型;利用该模型通过随机数机制得到幻影节点的随机有向漫步跳数,使用概率转发路由把数据包从幻影节点转发到集合节点,减少重叠路径发生的概率,提升源节点隐私位置信息的安全系数。实验结果表明,无线传感器网络源节点隐私位置信息保护方法可以有效降低路径重复概率和数据包传输时延,最大程度保证源节点的隐私安全,且网络能耗较小,具备极高的实用性。In order to ensure that the location of the source node in the wireless sensor network is not maliciously disclosed,a method of protecting the private location information of the source node in the wireless sensor network is put forward.Based on the model of panda-hunter location privacy protection,a model of a six-tuple system to defend against attacks was constructed.Based on this model,the random number mechanism was adopted to get the random directed walk hops of the phantom node.Moreover,the forwarding-probability route was used to transmit the data packets from the phantom node to the aggregation node,so as to reduce the probability of overlapping paths and improve the security factor of privacy location information.Experimental results show that the proposed method can effectively reduce the repetition rate of the path and the transmission delay of the data packet,so as to ensure the privacy security of the source node to the greatest extent.Meanwhile,the network energy consumption is low,so this method has high practicability.
