Recent Advances in Wireless Indoor Localization Techniques and System

Abstract

The advances in localization based technologies and the increasing importance of ubiquitous computing and context-dependent information have led to a growing business interest in location-based applications and services. Today, most application requirements are locating or real-time tracking of physical belongings inside buildings accurately; thus, the demand for indoor localization services has become a key prerequisite in some markets. Moreover, indoor localization technologies address the inadequacy of global positioning system inside a closed environment, like buildings. Based on this, though, this paper aims to provide the reader with a review of the recent advances in wireless indoor localization techniques and system to deliver a better understanding of state-of-the-art technologies and motivate new research efforts in this promising field. For this purpose, existing wireless localization position system and location estimation schemes are reviewed, as we also compare the related techniques and systems along with a conclusion and future trends.

Indoor Positioning: Opportunities and implementation strategies of Bluetooth Low Energy

“…Indoor-Atlas™ (https://www.indooratlas.com) attempts to do the same thing using magnetic field variables, for example. The similarity between the measurements and points in the database can be assessed by calculating the least square error or k-nearest neighbour, or by using sophisticated approaches like artificial neural networks, Bayesian inference, or support vector machine (SVM) (Farid, et al 2013). Using the RSSI as the decisive parameter here will again result in the question of how stable it is.…”

Indoor Fingerprint Positioning Based on Wi-Fi: An Overview

“…To date, most of the indoor positioning methods are based on fingerprint matching technology combined with other methods [26]. With further study, researchers have used many ways to improve fingerprint matching technology across all aspects.…”

A State-of-the-Art Survey of Indoor Positioning and Navigation Systems and Technologies

“…The RF system has the benefits of its signal being able to penetrate walls and obstacles leading to a wider coverage area, as well as reusing existing RF infrastructures resulting in a relative cost reduction (Gu et al, 2009;Farid, Nordin, & Ismail, 2013). These benefits have attracted researchers to the RF positioning system thus resulting in its categorisation as proximity detection and RSSI measurement systems.…”
