摘　　要：无线传感器网络由各种传感器组成,它们被部署在各种应用场景中并监控各种物体目标.然而,它也面临着诸多安全威胁,比如节点位置安全.为了解决这个问题,提出了一种基于随机游走的多分支端到端位置隐私保护方法.该方法通过设置多个代理源节点或代理基站来隐藏真实源节点或基站的位置.其中,真实源节点随机选择多个邻居作为接收器,直到数据包被发送到代理源节点.另外,代理源节点是随机选择的,这样可以使敌手很难获得真实源节点的准确位置信息.同时,基站周围设置了多个代理基站,通过代理基站转发数据包,改变路由策略来干扰敌手.通过分析和仿真实验,所提方法能够降低通讯消耗和传输延迟,并提高源节点和基站的安全.Wireless sensor networks are composed of various sensors, which are deployed in various application scenarios and monitor various object targets. However, it also faces many security threats. For instance, the location security of nodes. To solve this problem, we propose a multi-branch end to end location privacy protection scheme based on random walk. This method hides the location of real source or real sink by setting multiple proxy source nodes or multiple proxy sinks. The real source node randomly selects multiple neighbors as receivers until the packet is sent to the proxy source node. In addition, the proxy source node is chosen randomly, which makes it difficult for the adversary to obtain the location information of the real source node. At the same time, the scheme sets up multiple proxy sinks around the real sink to interfere with the adversary by changing routing strategy. Through analysis and simulation experiments, this scheme can reduce communication consumption and transmission delay, and improve the security of source nodes and base stations.
