Pyramid Architecture Search for Real-Time Image Deblurring

Wei Liu, Kaicheng Yu

Multi-scale and multi-patch deep models have been shown effective in removing blurs of dynamic scenes. However, these methods still suffer from one major obstacle: manually designing a lightweight and high-efficiency network is challenging and time-consumi ...

Hierarchical Routing Over Dynamic Wireless Networks

Matthias Grossglauser, Suhas Diggavi, Dominique Florian Tschopp

The topology of a mobile wireless network changes over time. Maintaining routes between all nodes requires the continuous transmission of control information, which consumes precious power and bandwidth resources. Many routing protocols have been developed ...

Energy Efficient Offloading of 3G Networks

Jean-Yves Le Boudec, Nikodin Ristanovic

A huge increase in the amount of data consumed by smartphone users is becoming a serious problem for mobile operators. In three years, mobile data traffic in the AT&T's network rose 5000%. The US operators invest 50 billion dollars in their data networks e ...

The impact of mobility on the time complexity for deterministic broadcasting in radio networks

André Schiper, David Cavin, Yoav Sasson

We study the time complexity for deterministic broadcasting algorithms in mobile radio networks. The broadcast operation consists of a source node successfully communicating its message to every other node. In multi-hop radio networks such as MANETs, the m ...

Image-Based Mobile Service: Automatic Text Extraction and Translation

Jérôme Berclaz

We present a new mobile service for the translation of text from images taken by consumer-grade cell-phone cameras. Such capability represents a new paradigm for users where a simple image provides the basis for a service. The ubiquity and ease of use of c ...

Designable Visual Markers

Jeffrey Huang, Enrico Costanza

Visual markers are graphic symbols designed to be easily recognised by machines. They are traditionally used to,track goods, but there is increasing interest in their application to mobile HCI. By scanning a visual marker through a camera phone, users can ...

Predicting User-Cell Association in Cellular Networks from Tracked Data

Jean-Yves Le Boudec

We consider the problem of predicting user location in the form of user-cell association in a cellular wireless network. This is motivated by resource optimization, for example switching base transceiver stations on or off to save on network energy consump ...

Eviction of Misbehaving and Faulty Nodes in Vehicular Networks

Jean-Pierre Hubaux, Imad Aad, Panagiotis Papadimitratos, Maxime Raya, Daniel Jungels

Vehicular Networks (VNs) are emerging, among civilian applications, as a convincing instantiation of the mobile networking technology. However, security is a critical factor and a significant challenge to be met. Misbehaving or faulty network nodes have to ...

Wireless Operators in a Shared Spectrum

Jean-Pierre Hubaux, Mark Felegyhazi

So far, cellular networks have been operated in "private" frequency bands. But recently, several researchers and legislators have argued in favor of a more flexible and more efficient management of the spectrum, leading to the possible coexistence of sever ...

Life cycle assessment of mobile telephone networks, with focus on the end-of-life phase

Wolfram Scharnhorst

Mobile communication, in particular mobile telephony, is a service whose nonexistence nowadays is unimaginable. The ongoing, ever increasing penetration of mobile communication equipment, presently intensified by the transition from second generation1 to t ...
