We present a reliable method of PHY-layer fingerprinting of IEEE 802.15.4-conformant nodes with commodity digital radio chips widely used in building inexpensive IEEE 802.15.4-conformant devices. Typically, PHY-layer fingerprinting requires software-defined radios that cost orders of magnitude more than the chips they can fingerprint; our method does not require a software-defined radio and use...

Trustworthy location information is important because it is a critical input to a wide variety of location‐based applications. However, the localization infrastructure is vulnerable to physical attacks, and consequently, the localization results are affected. In this paper, we aim to achieve robust localization under infrastructure attacks. We first investigated the impact of infrastructure att...

Fingerprint Abstraction Layer for Linux Daniel Drake Supervisor: Toby Howard April 28, 2008 Fingerprint scanners are popular consumer computing products, but they are generally unusable under Linux-based operating environments. My project implements Linux support for a range of USB fingerprint scanners, allowing for fingerprint-based authentication capabilities. The source code for the software...

Location fingerprinting in wireless LAN (WLAN) positioning has received much attention recently. One of the key issues of this technique is generating the database of ‘fingerprints’. The conventional method does not utilise the spatial correlation of measurements sampled at adjacent reference points (RPs), and the ‘training’ process is not an easy task. A new method based on kriging is presente...

One of the most significant elements of context-awareness in ubiquitous environments is mobile device localization. To obtain the accurate location information for indoor environments is a challenging problem. There have been a number of attempts to design systems for indoor localization using different wireless sensing techniques. Signal strength (SS) approaches are easy to implement in the ex...

With the advancement of wireless technology even more wireless sensor network (WSN) applications are gaining ground. Their field of application is increasingly widening. This paper examines the WSN application which allows indoor localization based on the Fingerprint (FP) method. The communication between the modules was monitored during the experiment whereby the received radio signal strength...

FeiYangchangweiyan capsule (FY capsule), a traditional Chinese medicinal preparation consisting of three medicinal herbs, has been used to treat bacterial dysentery, acute, and chronic gastroenteritis for several decades. In this study, a novel, convenient, accurate, and valid method was developed by using high-performance liquid chromatography (HPLC) coupled with diode array detection...

ABSTRACT Radio Frequency Fingerprinting (RFF) is a technique, which has been used to identify wireless devices. It essentially involves the detection of the transient signal and the extraction of the fingerprint. The detection phase, in our opinion, is the most challenging yet crucial part of the RFF process. Current approaches, namely Threshold and Bayesian Step Change Detector, which use ampl...

Wireless network on chip (WiNoC) is one of the promising on-chip interconnection networks for on-chip system architectures. In addition to wired links, these architectures also use wireless links. Using these wireless links makes packets reach destination nodes faster and with less power consumption. These wireless links are provided by wireless interfaces in wireless routers. The WiNoC archite...
