Abstract

An indoor positioning method detects a moving object defines a possible location area of the moving objects according to errors calculated by RSSI values of the moving object, and calculates RSSI moving vectors between the moving object and wireless devices according to the RSSI values to predict an exact position of the moving object according to the dependency of the RSSI moving vectors and relative angular positions of the moving object. The high relevance feature between CCI of multi-nodes and CINR is transformed as vectors and the vectors are compared with the RSSI moving vectors to calculate a RMSE value. When the root mean square error is less than a preset threshold value, the exact position of the moving object can be obtained.
