This paper investigates how to optimize the fingerprints reporting strategy to improve
localization accuracy, and how the optimal strategy theory can be utilized to streamline the …

Sniffing is cost-efficient and trouble-less method for capturing Wi-Fi traces within an area of
interest. However, a sniffer is likely to miss Wi-Fi packets because of inherent characteristics …

While WiFi monitoring networks have been deployed in previous research, to date none
have assessed live network data from an open access, public environment. In this paper we …

In this paper, we present a WiFi-based intrusion detection system called Wi-Alarm. Motivated
by our observations and analysis that raw channel state information (CSI) of WiFi is sensitive …

The Internet of Things (IoT) has boomed in recent years, with an ever-growing number of
connected devices and a corresponding exponential increase in network traffic. As a result …

Active scanning (AS) is a mechanism provided by the 802.11 standard by which WiFi clients
proactively search for access points (APs) in their vicinity. To do so, a client sends out a …

Wireless networks are ubiquitous nowadays and play an increasingly important role in our
everyday lives. Many emerging applications including augmented reality, indoor navigation …

Device-free indoor localization (DFIL) system can locate the position of human body in the
indoor environment by observing the changes in the received signal strength indicator …

Recent advances in the Internet of Things are leading to a proliferation of smart devices in
our daily life. Having so many connected devices around us potentially introduces new …

Tracking in dense indoor environments where several thousands of people move around is
an extremely challenging problem. In this paper, we present a system—DenseTrack for …
