摘　　要：针对多源节点的情况下的无线传感器网络(WSNs)端到端位置隐私保护进行研究,提出了一种基于双向树形拓扑结构的隐私保护方案(BTBLPS)。该方案采用最短路径方式进行真实数据包传输,然后在最短路径的交叉点上产生双向的假包传输分支。其中,临近源节点一侧分支上的假包传输方向是从分支末端节点传输到交叉点,而临近基站的一侧恰好相反,以此来达到同时对源节点和基站的位置隐私进行保护的目的。理论分析与仿真结果表明:所提的方案是可行的,并且具有良好的安全性能。Research on end-to-end location privacy protection in case of multi-source node in WSNs,propose a privacy protection scheme based on bidirectional tree topology（ BTBLPS）. The scheme adopts the shortest path method to transmit real data packets, and then on intersection of the shortest path produce fake packet transmission branch of bidirectional. Among them,fake packet transmission direction of branch near source node is from branch node at the end to intersection,and the side near base station,is contrary,in order to realize location privacy protection of source node and base station at the same time. Theoretical analysis and simulation results show that the proposed scheme is feasible,and has good safety performance.
