An Overview of Indoor Localization Technologies: Toward IoT Navigation Services

Localization system is a process of monitoring any area or object using any known information gathered from different sources such as wired or wireless networks. Internet of Things (IoT) technology plays a more significant role, which directly affects our lives. Navigation IoT based system is becoming a very appealing research topic nowadays since it is used in various context-aware and localization-aware applications that cover many fields such as tracking, healthcare, or security. Moreover, this field has taken so much attention lately since there is continuous progress in sensing technologies and computing capabilities. This paper provides a brief review of the indoor localization technologies used for IoT-based navigation systems. This review gives fundamental guidelines for designing an intelligent indoor localization system.
