中文摘要：

对无线传感器网络中的定位问题进行了研究，提出一种基于移动beacon协助的定位方法，该方法仅使用一个移动beacon即可完成对整个无线传感器网络的定位。给出两种beacon移动方式来进行定位，经过大量详实的仿真实验，验证了方法的有效性及定位的高精确度，可以将平均误差缩小到30厘米。

英文摘要：

This paper focuses on the localization issue in WSNs and proposes a mobile beacon - assisted localization approach, which uses only one mobile beacon to localize all sensor nodes in whole network. We present two movement patterns of beacon for locating. Great deals of thorough and solid simulations were conducted and their results validate the effectiveness of the method and high localization accuracy, the average error can be reduced to less than 30cm.
