Abstract:In indoor location, the accuracy of positioning is affected by the environment.This paper proposes a method to adapt to the changing of the environment.This method is improved on the base of the fingerprint database.In order to predict the real-time signal strength,it adds some reference points in off-time stage,and establishes relation of the signal strength of the reference points and mobile terminals.And in order to decrease the error of the relation,a sub-regional model is proposed.In real-time positioning stage,it can determine the location of mobile terminal by comparing the prediction signal strength with the real-time signal strength.
