Abstract

Aiming at the problems of low location accuracy, poor stability and low real-time performance in traditional WLAN fingerprint positioning algorithm, this paper proposed a WLAN indoor positioning algorithm based on CMAES-SVR. Firstly, the algorithm statistically analyzed the received signal strength(RSS) of access point(AP) and used the Gaussian filter to pretreat the RSS signal. It adopted the K-means clustering algorithm to partition the location area of original fingerprint database. Secondly, the covariance matrix adaptive evolutionary strategy(CMAES) optimized the support vector regression(SVR) parameters so as to establish the CMAES-SVR indoor positioning learning model. This model constructed the nonlinear mapping relationship between RSS signal and physical location in each sub location. Finally, the algorithm determined the cluster of the test points and carried out the regression prediction according to the trained CMAES-SVR model. The experimental results show that compared with WKNN, traditional SVR and PSO-SVR algorithm, the algorithm improves location accuracy, stability and real-time performance.
