摘　　要：无线传感器网络中源节点位置隐私变的越来越重要。针对这一问题提出了基于假包的单个虚拟圆环路由协议。同时针对虚拟圆环节点失效这一问题,提出了基于假包的多个虚拟圆环策略。采取敌人的平均追踪时间作为主要的衡量指标。仿真结果显示,单个虚拟圆环陷阱路由协议策略可以获得较长的安全时间,多个虚拟圆环策略可以获得比单个虚拟圆环陷阱路由协议更优越的效果。Source location privacy becomes more and more important in wireless sensor networks. Single virtual cir-cle rooting method based on fake package（SVCRM）is presented. Meanwhile an optimized SVCRM method calledmultiple virtual circle routing method based on fake package（MVCRM）is presented for the failure of the nodes onthe virtual ring. The adversary＇s average trace-back time is taken as the uppermost metric. The simulation resultsshow that SVCRM achieves a longer ATT than other methods,and that MVCRM performs better than SVCRM.
