“…Consequently, an effective attendee's location and tracking solution might be implemented, aiming, for example, at the intelligent management of user flows inside the building. The present experimental results in [128], where three LEDs placed in the receiver's LOS, can achieve a positioning localization accuracy of 18 cm. Aside from that, the solution offers plenty of additional advantages, including high transmission bandwidth, relatively low cost, and radiation-free operation.…”

<p>The number of connected mobile devices and Internet of Things (IoT) is growing around us, rapidly. Since, most of the people daily activities are relying on these connected things or devices. Specifically, this past year (with COVID-19) changed daily life in abroad and this is increased the use of IoT enabled technologies in health sector, work, and play. Further, the most common service via using these technologies is the localization/positioning service for different applications including: geo-tagging, billing, contact tracing, health-care system, point-of-interest recommendations, social networking, security, and more. Despite the availability of a large number of localization solutions in the literature, the precision of localization cannot meet the needs of consumers. For that reason, this paper provides an in-depth investigation of the existing technologies and techniques in the localization field, within the IoT era. Furthermore, the benefits and drawbacks of each technique with enabled technologies are illustrated and a comparison between the utilized technologies in the localization is made. The paper as a guideline is also going through all of the metrics that may be used to assess the localization solutions. Finally, the state-of-the-art solutions are examined, with challenges and perspectives regarding indoors/outdoors environments are demonstrated.</p>

An optical wireless positioning system that uses white light-emitting diodes (LEDs) based on Visible Light Communication (VLC) is presented in this paper. In the proposed system, four LEDs are employed for illumination and communication. The trilateration technique is used for determining the receiver's location and the practical Received Signal Strength (RSS) measurements are used for distance estimation. The impact of ambient light on Signal-to-Noise-Ratio (SNR) is studied by taking into consideration the first-order light reflection off of the ceiling, floor, and walls for channel modeling with both direct and indirect sunlight exposure. A modeling equation from the RSS measurements is proposed. The results show that the illuminance in all of the places in the room can be satisfied. Furthermore, the average positioning error by adopting the derived equation and trilateration technique was an error of less than 3 cm.

An interacting multiple model based on unscented Kalman filter (IMM-UKF) is widely applied to positioning and tracking targets in various tracking scenarios. At the same time, visible light positioning (VLP) is developing rapidly due to the low cost and accuracy. Therefore, indoor positioning and tracking based on VLP combined with the IMM-UKF has attracted considerable interest. However, existing algorithms work on the assumption that the light-emitting diodes used for tracking are all point light sources, which ignores the geometry of these transmitters and results in low tracking accuracy. To overcome this problem, this paper proposes an innovative tracking algorithm based on VLP. This algorithm considers the shapes of the lights in combination with existing tracking algorithms, such as IMM-UKF. Simulation results show that in a standard Gaussian noise environment, the larger the transmitter is, the more meaningful the proposed algorithm is.
