一种鲁棒性强的无线传感器网络位置隐私保护方案

传统无线传感器网络（WSNs）位置隐私保护方案难以解决安全性与网络能耗之间的均衡,为了提高网络隐私信息的安全性,提出一种鲁棒性强的无线传感器网络位置隐私保护方案.首先通过增加伪源节点和伪汇聚节点防止攻击者获得关键节点的位置信息;然后采用伪汇聚节点分组、概率丢弃冗余数据包降低网络资源消耗;最后在Matlab 2012平台下进行仿真对比实验.结果表明：该方案可以提高网络攻击事件检测率,降低网络时延,有效地保护源节点和汇聚节点的位置隐私.

A location privacy protection scheme with strong robustness for WSNs

Traditional location privacy protection scheme for wireless sensor networks （WSNs）can not get well balance between security and network energy consumption, in order to improve safety of privacy information of WSNs, a robust location privacy protection scheme for WSNs is proposed. Firstly , by increasing pseudo source node and pseudo sink node to prevent attacker to obtain position information of key nodes;secondly, pseudo sink node are divided into two groups, throw redundant packets probabilistically to reduce network source consumption ; finally, simulation comparison experiments are carried out on Matlab 2012 platform. Results： show that this proposed scheme can improve attack detection rate of network and reduce network delay, effectively protect location privacy of source node and sink node.
