摘要
根据无线传感器网络中RSSI的信号传播的特性,给出了基于RSSI的室内节点的测距模型。随着距离的增加,信号衰减越来越不明显,对测距造成的误差也越来越大,给出了室内空间附加因子路径传播模型,并与常用的阴影模型做了对比,实验结果表明,该模型有较高的精度。
According to the wireless sensor network signal propagation characteristics of the RSSI, an indoor node location model is given based on RSSI. Along with the increase of distance, signal attenuation will be less and less obvious, and the location error caused more and more big, this paper gives the interior space additional factor path propagation model, and made the contrast with the shadow of common model, the experimental results show that the model have high accuracy.
