A Wireless Biosensing Device

2006 1st Electronic Systemintegration Technology Conference, 2006
In this work we have evaluated the feasibility of magnetostrictive materials in the realization of a wireless biosensing device. The measuring concept is composed of two major components that are the miniaturized sensor element and the external instrumentation for the electromagnetic excitation of the sensor and for receiving the bioinformation.

Wireless Device-to-Device Communications and Networks

2015
Covering the fundamental theory together with the state-of-the-art in research and development, this practical guide provides the techniques needed to design, analyze, and optimize device-to-device (D2D) communications in wireless networking. With an ever-increasing demand for higher data rate wireless access, D2D communication is set to become a key ...

Integrating wireless devices into the IT curriculum

Proceedings of the 6th conference on Information technology education, 2005
Wireless devices, mobile systems - they are all the rage. IT programs face the question, "Where can we introduce these topics into the existing program if a new, dedicated course is not immediately available?" The IT program at Texas Christian University (TCU) has addressed the issue by including wireless device programming in the web technologies ...

Optimal caching strategy in device-to-device wireless networks

2018 IEEE Wireless Communications and Networking Conference Workshops (WCNCW), 2018
In this paper, we consider a device-to-device (D2D) wireless network, in which the wireless users act as helpers to provide the nearby users requested files through the D2D communication. We study an optimal caching strategy to minimize the outage probability where the co-channel interference among different D2D links is considered.

Wireless Handheld Devices Become Trusted Network Devices

Information Systems Security, 2007
In the world of information technology, a security model is only as secure as its weakest link. There are several layers of security and different measures that can currently be implemented. However, they lack coordination, and therefore potential security breaches might compromise the network.

Multimedia transmission over device-to-device wireless links

2016 IEEE International Conference on Multimedia and Expo (ICME), 2016
This paper studies the performance of hierarchical modulation-based image transmission in device-to-device (D2D) cellular wireless networks under constraints on both transmit and interference power levels. Hierarchical quadrature amplitude modulation (HQAM) is considered in which high priority (HP) data is protected more than low priority (LP) data. In

Device-to-Device Communication in Wireless Mobile Social Networks

2014 IEEE 79th Vehicular Technology Conference (VTC Spring), 2014
Wireless mobile social networks have been introduced to consider characteristics of mobile user's behaviors for network configuration. The device-to-device (D2D) communication is to increase the network spectral efficiency by allowing users to communicate directly with the corresponding destinations.

A Reconfigurable Cross-Connected Wireless-Power Transceiver for Bidirectional Device-to-Device Wireless Charging

IEEE Journal of Solid-State Circuits, 2019
This paper presents a reconfigurable cross-connected (CC) wireless power transceiver (TRX) operating at 6.78 MHz and implemented for bidirectional device-to-device (D2D) charging with high efficiency and small system volume. We propose, for the first time, a CC topology applied to a differential class-D power amplifier for significant switching loss ...

Wireless Handheld Devices and the Web

2001
PDA access to the World-Wide Web pose a variety of difficulties for users. The small screen quickly renders Web pages confusing and cumbersome to peruse. Inputting information by pen is time consuming and error-prone. The download time for Web material to radio linked devices is still much slower than landline connections. The standard browsing process

Device Authentication In Wireless And Pervasive Environments

Intelligent Automation & Soft Computing, 2010
Abstract Security can only be guaranteed as long as the hardwaze and other key parameters, including software components, secret keys etc, of a device remain genuine and unrnodified. Under this context, device authentication must be considered as a key security issue, complementary and of equal importance to user authentication, in today’s wireless and
