This paper introduces a review article on indoor localization techniques and technologies.
The paper starts with current localization systems and summarizes comparisons between …

Network localization and navigation (NLN) is a promising paradigm, in which mobile nodes
exploit spatiotemporal cooperation, to provide reliable location information for a diverse …

In this paper, we present a Bluetooth Low Energy (BLE) based indoor positioning system
developed for monitoring the daily living pattern of old people (eg people living with …

Indoor localization is one of the key enablers for various application and service areas that
rely on precise locations of people, goods, and assets, ranging from home automation and …

Recently, reconfigurable intelligent surface (RIS), which operates with the aim to manipulate
multi-path signals, has been widely considered for wireless communications. In this letter …

This paper presents a joint synchronization and localization algorithm based on the time-
difference-of-arrival (TDOA) for asynchronous Wireless Sensor Networks (WSNs), where the …

This paper considers distributed estimation methods to enable the formation of Unmanned-
Aerial-Vehicles (UAVs) that track a moving target. The UAVs (or agents) are equipped with …

Localization is one of the current challenges in indoor navigation research. The
conventional global positioning system (GPS) is affected by weak signal strengths due to …

An effective indoor localization method of hybrid RSSI/TDOA is proposed to reduce the big
errors occurred during indoor RSSI localization and high cost paid by TDOA localization. It …

Positioning between multiple users without any given infrastructure is essential for many
applications, such as emergency response in disaster areas. Traditional approaches based …
