摘　　要：针对无线传感器网络中的源节点位置隐私安全保护问题进行了研究,设计了一种基于随机角度和圆周路由的源位置隐私保护策略BRACRS。该策略通过三个阶段进行路由,即基于角度的幻影路由阶段、圆周路由阶段和最短路径路由阶段。采用均匀划分法使幻影节点基于不同的角度动态随机产生,传感器节点利用充裕区域的能量形成动态的、路径足够长的路径,从而保护源节点的位置隐私。分析结果表明,与现有PUSBRF和HBDRW等保护方案相比,在不显著增加通信开销的情况下,能大大延长网络的平均安全时间,增强源位置隐私的安全性。Aiming at the problem of source location privacy in wireless sensor networks,this paper proposed a source location privacy protection strategy called BRACRS（ based on random angle and circumferential routing）. This strategy was routed through three stages： phantom routing stage,circular routing stage and shortest path routing stage. To protect the source node location,phantom nodes could be generated by different angles dynamically and randomly,sensor nodes form dynamic and long enough path by use of energy in abundant areas. Analysis show that,compared with existing privacy protection strategies,including PUSBRF and HBDRW,etc,the strategy not only extends the average network security time greatly,but also improves security of source node location privacy significantly without increasing communication overhead too much.
