Indoor Localization Techniques for Smart Building Environment

Abstract “Knowing the Location” and “Determining the Location” are the essential requirements of constructing a smart building. GPS technology, which is often used for the purpose of positioning, cannot be used efficiently while performing position detection indoors because of the losses occurring in the signal propagation. At the same time, the object of sensors, Bluetooth, IrDA and RFID devices which are commonly used in a building, and bandwidth constraints makes such location detection more difficult because of possible energy consumption and limited memory capacity. Since WiFi technology which will probably be used in nearly all Smart Buildings, Indoor localization algorithms have been surveyed and requirements which are essential for obtaining Internet of Things (IoT) technology have been researched, and a context-based approach for a Smart Building which has got IoT structure is proposed.
