Abstract	:	Due to the lack of accuracy and robustness, Indoor Positioning System has now become a major with huge concerns worldwide especially with the rapid increase in multimedia services and data. Therefore, there is a need to enhance the accuracy of indoor localization by exploiting the capability of the available technologies. In this paper, a hybrid indoor localization system that is based on Wi-Fi and Bluetooth Low Energy (BLE) communication technologies is proposed. The main infrastructure of the proposed system is to use Wi-Fi tritleration method to determine the position of users at indoor areas based on Wi-Fi signal strengths. Then, the position obtained by the Wi-Fi tritleration method is used to check whether the user exists within one of the indoor locations supported by BLE or not. This enables the localization process with beacons to get higher indoor positioning accuracy than Wi-Fi. Experimental results show that the proposed system can achieve average error of less than one meter compared with the existing indoor positioning systems. This vindicates the suitability and reliability of the proposed system.
