Design and Implementation of Indoor Localization System Based on Improved EWKNN Algorithmk
In this study,an indoor localization system based on the improved EWKNN algorithm is proposed,which incorporates online AP selection and the EWKNN algorithm with improved weighting coefficients for indoor localization.In addition,this paper describes the development process of the indoor localization system based on the improved EWKNN algorithm,covering the database establishment method,the improvement of the EWKNN algorithm,the testing and execution,and the demonstration of the Android client.The test results of the system show that the positioning system is able to locate effectively in indoor barrier-free environments with ex-cellent real-time performance and high positioning accuracy,and is able to adapt to the positio-ning requirements of a variety of indoor scenarios.
