据此建立了RSSI的变化和区域内每个像素阴影衰落的线性模型
) Abstract: Using radio tomographic imaging method to locate the target in the area consisting by wireless sensor network is presented
Some links between nodes experience dramatic change because of shadowing loss caused by target's obstruction
Therefore, this paper illustrates a linear model relating the change of RSSI to the attenuation within each pixel; gives the minimum mean square error solution for the model; establishes a experimental platform with wireless sensor network to evaluate the effectiveness of the method
The experimental results show that the average location error of the algorithm for a single target is only 0
