To fully realize the potential of autonomous aerial vehicles, a reliable, robust, and accurate
navigation system is required. Current technologies composing such a system include stand …

Remarkable progress in radio frequency and micro-electro-mechanical systems integrated
circuit design over the last two decades has enabled the use of wireless sensor networks …

Among the current indoor positioning technologies, Bluetooth low energy (BLE) has gained
increasing attention. In particular, the traditional distance estimation derived from aggregate …

The motivation of this work is to help outpatients find their corresponding departments or
clinics, thus, it needs to provide indoor positioning services with a room-level accuracy …

This work addresses the problem of target localization in adverse non-line-of-sight (NLOS)
environments by using received signal strength (RSS) and time of arrival (TOA) …

LoRa is a popular Low-Power Wide-Area Networking (LP-WAN) technology that allows
devices powered by a ten year AA battery to connect to radio infrastructure miles away. One …

We propose a novel localization method using angle-of-arrival (AoA) measurements with
two-step error variance-weighted least squares (TELS). The first step is to estimate a …

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 …

A multitude of applications based on unmanned aircraft vehicles (UAVs), in conjunction with
the UAVs' diminishing costs and increasing capabilities, present a major threat to public …

Although wireless fingerprinting has been well researched and widely used for indoor
localization, its performance is difficult to quantify. Therefore, when wireless fingerprinting …
