This paper provides a comprehensive survey of indoor localization systems and technologies, focusing on techniques such as Angle of Arrival (AoA), Time of Flight (ToF), Return Time of Flight (RTOF), and Received Signal Strength (RSS). The survey covers a wide range of technologies including WiFi, Radio Frequency Identification Device (RFID), Ultra Wideband (UWB), Bluetooth, and systems proposed in recent literature. The paper highlights the strengths of existing systems and evaluates them from the perspectives of energy efficiency, availability, cost, reception range, latency, scalability, and tracking accuracy. It also discusses the challenges and opportunities in leveraging IoT for indoor localization, emphasizing the need for collaboration between short- and long-range IoT technologies to meet diverse localization requirements. The paper aims to serve as a starting point for further research in indoor localization, providing a detailed overview of different aspects and technologies involved.This paper provides a comprehensive survey of indoor localization systems and technologies, focusing on techniques such as Angle of Arrival (AoA), Time of Flight (ToF), Return Time of Flight (RTOF), and Received Signal Strength (RSS).
