Research of target localization and tracking is always a remarkable problem in the
application of wireless sensor networks (WSNs) technology. There are many kinds of …

Indoor localization is a fundamental task to many real-world applications, which however
remains unresolved, especially with commodity WiFi Access Points (APs). In this paper, we …

In recent years, decimeter-level accuracy in WiFi indoor localization has become attainable
within controlled environments. However, existing methods encounter challenges in …

Wireless sensing is an emerging technology that can obtain rich context information of
human targets in a contact-free manner. Though promising, a missing component of current …

Accurate road networks play a crucial role in modern mobile applications such as navigation
and last-mile delivery. Most existing studies primarily focus on generating road networks in …

Wi-Fi signals contain information about the surrounding propagation environment and have
been widely used in various sensing applications such as gesture recognition, respiratory …

Wi-Fi fingerprinting system in the long term suffers from gradually deteriorative localization
accuracy, leading to poor user experiences. To keep high accuracy yet at a low cost, we first …

We propose a novel sensorless approach to indoor localization by leveraging natural
language conversations with users, which we call conversational localization. To show the …

We organized an online fingerprint-based indoor localization competition in 2021. It
attracted 1,170 teams worldwide. The teams were provided with a 60 GB dataset including …
