摘　　要：定位技术是其它无线传感器网络技术的基础,基于节点位置信息的监测行为的安全性尤为重要。针对无线传感器网络RSSI定位技术,分析虫洞攻击对定位的影响,提出一种安全定位方法。采用倒数作为权值因子,并在RSSI定位测距阶段根据节点的物理特性过滤攻击节点,提出了通信范围受限特性、消息受限特性和接收消息唯一性,能够在提高定位精度的同时有效降低虫洞攻击对定位的影响;仿真结果表明:相对于传统的节点加密等方法,降低计算复杂度,减少节点能量消耗,延长网络生命周期。Localization technology is the basis of other wireless sensor network technologies. The security of monitoring behaviors based on the location information of nodes is especially important. Aiming at the RSSI localization process,the impact of wormhole attack on location was analyzed,and a secure localization method was proposed. The countdown was used as the weight factor,and the attack node was filtered according to the physical characteristics of the nodes in the RSSI ranging phase. The characteristics of restricted communication range,restricted message,and uniqueness of received message were proposed. It can effectively reduce the impact of wormhole attack in improving the positioning precision at the same time. The simulation result manifests that this method can cut down the amount of computation,reduce the energy consumption and prolong the network life cycle compared with the traditional node encryption method.
