A Comparative Survey on Indoor Object Location Tracking Techniques and Technologies

摘要

Indoor object location tracking has newly vouched an increment in Eagerness, owing to the probable extensive length of services it can deliver by universal connectedness and Internet of Things (IoT). In outdoor location, GPS technology is mostly used that can be found in Geographical Map. But GPS technology a dicey technique for fixing positions of objects in indoor location owing to lack of line of sight (LoS). We discuss different approaches, technique and technologies which are used in indoor positioning system such as Radio Frequency Identification Device (RFID), Ultra-Wideband (UWB), Received Signal Strength (RSS); based on like WiFi technology, Angle of Arrival (AoA), Time of Flight (ToF), Return Time of Flight (RTOF) and also highlight their energy efficiency, cost, reception range, availability, latency, tracking exactness and efficiency.
