中文摘要：
提出基于节点测距的无线传感器网络（wsN）入侵节点检测算法，用于检测无线传感器网络中是否存在外来的伪造节点。该算法运用节点自身的各种传感器进行节点间测距，通过综合分析测距结果保证该算法能成功检测到网络中存在的伪造节点，检测中不需要网络同步时钟和节点位置信息。该算法可适用于不同规模、不同应用的无线传感器网络。通过理论分析和仿真实验验证了该算法在无线传感器网络节点攻击检测中的有效性和可行性。
英文摘要：
To detect whether a forged node exists in Wireless Sensor Networks, an intrusion node detection algorithm based on node ranging in Wireless Sensor Networks （WSN） is proposed. The proposed algorithm can range between nodes using the various sensors of the node itself and can successfully detect forged node in the network through a comprehensive analysis of ranging results. The detection does not require the network synchronizing clock and the node position information. The algorithm is applicable to different sizes, different applications of Wireless Sensor Networks. Theoretical analysis and computer simulations verify the effectiveness and feasibility of the algorithm in Wireless Sensor Network node attack detection.
