As the number of indoor location based services increase in the mobile market, service providers demanding more accurate indoor positioning information. To improve the location estimation accuracy, this paper presents an enhanced client centered location prediction scheme and filtering algorithm based on IEEE 802.11 ac standard for indoor positioning system. We proposed error minimization filtering algorithm for accurate location prediction and also introduce IEEE 802.11 ac mobile client centered location correction scheme without modification of preinstalled infrastructure Access Point. Performance evaluation based on MATLAB simulation highlight the enhanced location prediction performance. We observe a significant error reduction of angle estimation.
