摘要：

针对无线传感网中现有信源匿名协议大都存在无法同时兼顾源位置匿名性、延迟和生存周期的问题，对数据混淆、虚假信息注入等方法在隐私性、网络性能等方面进行了分析，在此基础上首次提出了基于匿名量化动态混淆环的源位置隐私保护协议 ADRing：以能量均衡消耗确保的动态混淆环以及相应基于区位象限的匿名度量化评估机制来高效地保护信源节点位置隐私。仿真实验结果表明，ADRing 相比于现有协议能明显改善网络能耗和延迟均衡性，延长网络寿命，能满足网络节点对于数据分组匿名性和延迟的不同需求。

Abstract:

Considering the conflicts among anonymity, network load and transmission latency for most of the existing event source-location privacy (SLP) in wireless sensor network (WSN).Firstly,the effect of the data mixing and fake packet injec-tion on the privacy and network performance was analyzed. Then, the anonymity-quantified dynamic mix-ring-based source-location anonymity protocol(ADRing)was proposed, ADRing which was designed to achieve source anonymity and balance between network traffic and real event report latency through the dynamic mix-ring based packet confusion and the corresponding sector-based anonymity assess and the radius of non-uniform clusters. The simulation results demonstrate that ADRing is very efficient in balancing energy consumption and transmission latency, and can significantly prolong survival period of the network and ensure security as well as latency to satisfy the packets' requirements.
