Abstract
With a flourish of wireless technologies, indoor localization is becoming an emerging topic for crucial practical research including homeland security, police patrolling, machinery fault-detection, target tracking, etc. Generally speaking, indoor localization technology involves three primary types of methodologies, namely <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">range-based localization</i> , <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">fingerprint-based localization</i> and <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">inertial localization</i> . This paper is aimed to present an overview of these prominent indoor localization techniques and the state-of-the-art solutions. To manifest this important topic, the general localization mechanisms are analyzed. Finally, performance requirements such as accuracy, cost, robustness are presented for benchmarking localization system performances.
