動態環境無線網路定位法

The device is employed and named reference point, to replace traditional radio map to sense real-time fluctuation of received RF signal strength in a location of the environment. Based on characteristic of the reference point, an off-line calibration-free localization algorithm is responded. In addition, the mathematical model is applied to the localization algorithm so that achieving a higher degree of accuracy on location estimation. Finally, the practical experiments show that localization algorithms not only solving the problem for having huge calibration effort but also achieving a high degree of accuracy on location estimation.
