Study of Fingerprint Location Algorithm Based on Wifi Technology

Abstract

Aiming at the problem that the anti-disturbance poor ability of the wifi fingerprint location algorithm and the positioning accuracy to be improved. This paper takes the direction effect of the signal into consideration and establishes fingerprint database by using a new data acquisition and filtering techniques. At the same time, it uses dynamic joint WKNN algorithm and combines with two different ways of allocating weights to realize localization in the matching phase. Experimental results show that the proposed method can improve the stability and precision of positioning to a certain extent.
