该文章提出了一种自动虚拟的校正方法以及对应的定位算法，用于基于RSSI的无线定位领域中，可以提高定位精度。-In this paper,

we present an automatic virtual calibration method of the propagation model that does not require human intervention

therefore, can be periodically performed, following the wireless channel conditions. We also propose a novel RSSI-based

localization algorithm that selects the RSSI values according to their strength, and uses a calibrated propagation model to

transform these values into distances, in order to estimate the position of the mobile
