中文摘要：
为了有效解决无线传感器网络（WSN）节点定位精度和测距技术复杂性之间的矛盾,基于WSN随机分布特性和天线阵列几何结构约束,通过节点协同形成的虚拟天线阵列对WSN进行定位,提出了一种适于定位的虚拟阵列节点选择方法.仿真结果和理论分析表明,当波达角估计算法的性能满足要求时,该方法具有很强的可行性和优良的定位性能.
英文摘要：
In order to effectively overcome the contradiction between the accuracy of node localization and the complexity of ranging technology in wireless sensor network（WSN）,a new dummy array node selection method sui-table for localization is proposed based on the random distribution of WSN and the restricted geometry structure of sensor array.In this method,the dummy sensor array based on node cooperation is used to locate the sensor nodes in WSN.Simulated and analyzed results indicate that,when the estimation algorithm of the direction of arrival meets the capability requirements,the proposed method is feasible and accurate in localization.
