Abstract
An indoor positioning method detects a moving object defines a possible location area of the moving objects according to errors calculated by received signal strength indication (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 the Co-Channel Interference (CCI) of multi-nodes and the Carrier to Interference-plus-Noise Ratio (CINR) is transformed as vectors and the vectors are compared with the RSSI moving vectors to calculate a Root Mean Square Error (RMSE) value. When the RMSE value is less than a preset threshold value, an exact position of the moving object can be obtained.
