求翻译：传统的基于RSSI的定位过程中，未知节点根据接收到的信号强度，然后通过信号传播的经验模型，通过提前建立的离线数据库进行查表以找出该信号强度对应的位置坐标。另一种方法是通过信号传播理论模型，计算出该信号强度对应的传播距离，然后通过一种节点坐标的计算方法推算出节点的位置坐标。下面对信号传播的经验模型和理论模型分别进行介绍：是什么意思？

Rssi-based positioning, the unknown node based on the received signal strength, and then through the experience of the signal propagation model, ahead of established offline database look-up table to find out the coordinates of the position corresponding to the signal strength. Another method is the

Based on the traditional RSSI positioning process, an unknown nodes based on the strength of the signal received by a signal, and then spread the Experience Model, through the early establishment of off-line database for the tables to find the signal strength corresponds to the location coordinates.

The tradition based on in the RSSI localization process, the signal strength which the unknown node basis receives, then the proceed signal dissemination experience model, through the off-line database which establishes ahead of time carries on the table look-up to discover this signal strength corr
