Indoor Localization Based on Radio and Sensor Measurements

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
range-based localization
,
fingerprint-based localization
and
inertial localization
. 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.
