摘　　要：由于传统的无线传感器网络冗余节点识别方法忽略了节点的方向性,单纯依靠拓扑结构的关联规则进行节点定位,存在节点定位误差较大、节点识别精度较低的问题,提出基于TOPSIS算法的无线传感器网络冗余节点定位方法。该算法首先建立网络节点的方向虚拟坐标,通过拓扑保留图确定所有节点在图中的坐标;其次建立无线传感器网络冗余节点判断指标体系;最后利用TOPSIS算法判断节点冗余度,确定节点在拓扑保留图中的位置,完成无线传感网络中冗余节点定位方法的设计。仿真分析表明,应用所提方法对无线传感网络中冗余节点进行识别的逼近度最高为0.98,冗余节点定位准确率为95%,真阳性率为98%,假阳性率为2%,说明所提方法对于网络冗余节点的识别精度较高,识别效果较好。The traditional method of identifying redundant nodes in wireless sensor networks neglects the directionality of nodes and re-lies solely on the association rules of topological structures for node localization,resulting in problems of large node localization errors and low node recognition accuracy.Therefore,a wireless sensor network redundant node localization method based on TOPSIS algorithm is proposed.Firstly,the virtual coordinates of the network nodesdirections are established,the coordinates of all nodes in the graph are determined through topology preservation.Secondly,a redundant node judgment index system for wireless sensor networks is established.Finally,the TOPSIS algorithm is used to determine node redundancy and the position of nodes in the topology preservation graph,and the design of redundant node localization methods in wireless sensor networks is completed.Simulation analysis shows that the proposed method has a maximum approximation of 0.98 for identifying redundant nodes in wireless sensor networks,with a positioning accuracy of 95%,a true positive rate of 98%,and a false positive rate of 2%.This indicates that the proposed method has a high recognition accura-cy and good recognition effect for redundant nodes in the network.
