| 摘 要： | 针对无线传感器网络的节点自定位问题，提出一种利用单个移动信标的定位算法。该方法在传统Bounding Box定位方法的基础上，结合信标的实际通信区域，提出“O-区域”和“S-区域”的概念，通过对新接收到的信标位置分类讨论，进一步缩小未知节点的可能区域。通过仿真比较，验证了该方法的性能优于质心定位法和Bounding Box定位法，同时定位精度与移动信标的通信半径大小有关。 |

| Abstract: | Aimming at the node localization problem in wireless sensor networks,an algorithm using a single mobile beacon is proposed.Based on the traditional Bounding-Box localization method,the actual communication area of the mobile beacon is considered and the concept of "O-area" and "S-area" are proposed in the algorithm.New location information from the mobile beacon is classified and the potential area of unknown node is reduced.Simulation results show that the proposed algorithm had better performance than the centroid method and Bounding-Box method,and its localization accuracy is related to the communicating radius of the mobile beacon. |
| Keywords: | wireless sensor networks node localization mobile beacon radio irregularity |
