摘要: 针对无线传感器网络汇聚节点位置隐私安全问题,提出了一种基于安全区域的动态路由算法,通过在非安全区域内向安全区域概率性发送数据包与虚假数据包以及在汇聚节点周围形成环形汇聚区域等方法保护汇聚节点的位置信息。对提出的动态路由算法与现有的汇聚节点隐私保护算法进行性能比较,网络仿真实验结果显示本路由算法具有能耗小,网络时延小,数据传送成功率高等优点,可以实现汇聚节点位置隐私安全和网络能耗之间的较好均衡。

Abstract: In view of problems appear in location privacy protection for sink node of wireless sensor networks, a location privacy preserving routing algorithm for sink node based on security area was proposed. This protocol protected location privacy of sink node through methods such as sending real package or fake package probabilistic from safe area to unsafe area and forming a circular sink area around the sink node. Performance evaluation was compared between this proposed dynamic routing algorithm and existing one. Network simulation results show that the routing algorithm has advantages such as low energy consumption, small network delay, and high data transmission rate, and it can also make a good balance between location privacy protection of sink node and network energy consumption.

Key words: location privacy protection, fake package, secure area, circular sink area
