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 …

Wireless sensor networks (WSNs) have a vital role in indoor localization development. As
today, there are more demands in location-based service (LBS), mainly indoor …

Ubiquitous indoor environments often contain substantial amounts of metal and other similar
reflective materials that affect the propagation of radio frequency signals in important ways …

A hybrid RSS/AOA indoor localization method based on error variance and measurement
noise weighted least squares (ENWLS) is proposed. This method is based on three …

Traditional indoor localization techniques typically rely on a single communication source
such as RF signals, ultrasound, inertial sensors, and geomagnetic fields. In wireless sensor …

Wireless node localization is one of the key technologies for wireless sensor networks.
Outdoor localization can use GPS, AGPS (Assisted Global Positioning System)[6], but in …

With the rapid development of robotics, miniaturized and inexpensive robots have gradually
entered the public's field of vision. Smartphone-based robots have the potential to provide …

This paper proposed a novel trilateration algorithm for indoor localization based on received
signal strength indication (RSSI). Firstly, all the raw measurement data are preprocessed by …

In the case of a single scene feature, the positioning of an indoor service robot takes a long
time, and localization errors are likely to occur. A new method for a hybrid indoor localization …

In a Wireless Sensor Network (WSN), it is often necessary to know the accurate location of
one or more nodes. Various localization methods have been proposed, namely: TDOA, TOA …
