The homes, offices, and vehicles of tomorrow will be embedded with numerous "Smart Things," networked with each other and with the Internet. Many of these Things are embedded in the physical infrastructure, and like the infrastructure they are designed ...

We present a hybrid wired-wireless time synchronization method targeting enterprise WLAN networks to enable future deployments of distributed wireless PHY protocols. Our method synchronizes all network APs on the Ethernet backhaul using the IEEE 1588 ...

To overcome the drawbacks and security issues of traditional wireless and RF-based communication techniques, multiple alternative "wireless" communication methods have been investigated. Among them, capacitive touch communication which utilizes the ...

Securely transferring data between two devices that have never previously met nor shared a secret is a difficult task. Previous solutions to the problem are susceptible to well-known attacks or may require extensive infrastructure that may not be ...

The ubiquity of mobile camera devices has been triggering an outcry of privacy concerns, whereas privacy protection still relies on the cooperation of the photographer or camera hardware, which can hardly be guaranteed in practice. In this paper, we ...

The progression of wireless communication into lower power, smaller form factor devices has heralded the age of the Internet of Things (IoT). Predictions show the integration of IoT devices into all facets of our public and private lives. It is not hard ...

Along with the rapid development of human-computer interaction (HCI), controlling objects and smart devices remotely from afar has become the trend to satisfy the needs of consumers. Hand gesture recognition is among the methods that highly attract the ...

The ubiquity of mobile camera devices has been triggering an outcry of privacy concerns. In this demo, we introduce LiShield, which automatically protects a physical scene against photographing, by illuminating it with smart LEDs flickering in ...

Target material identification plays an important role in many real-life applications. This paper introduces a system that can identify the material type with cheap commercial off-the-shelf (COTS) RFID devices. The key intuition is that different ...

We introduce a lightweight, cost-effective, and portable solution for real-time peripheral oxygen saturation SpO2 measurement using photometric sensing through a smartphone's camera. Specifically, we design a hardware plug-in module that snaps onto the ...

The past decade's research in visible light positioning (VLP) has achieved centimeter location precision. However, existing VLP systems either require specialized LEDs which hinder large-scale deployment, or cameras which preclude continuous ...
