| 摘 要： | 无线传感器网络的节点自定位的技术主要有基于测距(Range-Based)的定位技术和距离无关(Range-Free)定位技术。该文主要研究了基于测距的无线传感器网络定位算法。在传统质心定位算法中,引入相对RSSI加权定位实现未知节点的位置估计。该方法每个锚节点的权值使用RSSI的相对位置值,每个锚节点的权值可以按线性或指数加权。

| Abstract: | The location techniques for WSN can be divided into two categories:Range-based approaches and Range-free approaches. The thesis mainly focuses the investigation on the range-based algorithms for WSN.Based on Traditional centoid localization,we introduce weighted centroid localization based on relative RSSI.Each anchor node is weighted by relative RSSI.The weight can be linear or exponents. |
