| 摘 要： | 针对目前无线定位技术及其算法进行了一定的研究,并提出了一种新的方法:阈值分段定位方法(Threshold Localization Method,TLM)。当目标节点和参考节点距离在阈值距离以内时采用改进的RSSI测距法,建立一个特定环境中的信号传播模型;当距离在阈值距离以外时,采用基于LQI指示的DV-Hop算法,在传统DV-Hop算法中引进LQI来改善定位精度。无线收发采用ZigBee无线通信技术。

| Abstract: | According to researches about current wireless localization algorithm and technology, a new method called TLM （Threshold Localization Method） is proposed. When the distance between beaconnodes and unknown-nodes is less than the threshold, an improved method on RSSI is used and a signal propagation model would be built. Otherwise, the DV-Hop algorithm based on LQI is used, the localization precision can be improved after LQI is involved. The technology of wireless communication used in this paper is ZigBee. |
