许多论文主要通过理论分析和计算机模拟的结果指出了基于tdoa的定位相对于基于rssi的定位的优越性，但很少有实验证实。通过实验比较了基于rsi的定位估计方法和基于TDOA的定位估计方法的性能，并详细讨论了它们的优缺点。结果表明，在目标节点和锚节点之间的直接链接经常被行走的人遮挡的拥挤区域，基于rssi的方法具有优势。
The superiority of TDOA-based localization over RSSI-based localization has been pointed out in many papers mainly by the results of theoretical analyses and computer simulations, but it has been rarely confirmed by experiments. This paper compares the location estimation performances between a RSSI-based method and a TDOA- based method by experiments and discusses their pros and cons in detail. It is shown that RSSI-based method is advantageous in the crowded location estimation area where the direct links between a target node and anchor nodes are frequently shadowed by walking men.
