Outtweeting the Twitterers - Predicting Information Cascades in Microblogs

Karl Aberer, Dipanjan Chakraborty, Wojciech Galuba, Zoran Despotovic

Microblogging sites are a unique and dynamic Web 2.0 communication medium. Understanding the information flow in these systems can not only provide better insights into the underlying sociology, but is also crucial for applications such as content ranking, ...

Performance Evaluation of a Multi-band UWB Location and Communication System Based on Modified Gegenbauer Functions

Ultra wide band (UWB) may offer very efficient solutions for various communication and sensing applications. Two approaches have emerged, which meet all the communication requirements: impulse and multi-band systems. The present work is concerned in the se ...

Source coding in sensor networks

Robert Konsbruck

Wireless sensor networks have emerged as versatile tools to monitor the evolution of physical fields over large areas by means of self-powered and low-cost sensing devices. Although their development was originally motivated by military applications, they ...

Distributed and Component Oriented Tools for Communication Networks Using Web Services

Sébastien Rumley, Christian Gaumier, Christophe Trefois

Modern communication networks are reaching a high level of complexity. As their global dimensioning and performance evaluation are very hard tasks, a multi-layer approach is generally applied to divide them in smaller problems easier to tackle. Within this ...

Adaptive video delivery using semantics

Olivier Steiger

The diffusion of network appliances such as cellular phones, personal digital assistants and hand-held computers has created the need to personalize the way media content is delivered to the end user. Moreover, recent devices, such as digital radio receive ...

Redundant Image Representations in Security Applications

Pascal Frossard, Pierre Vandergheynst, Philippe Jost

To be efficient, data protection algorithms should generally exploit the properties of the media information in the transform domain. In this paper, we will advocate the use of non-linear image approximations using highly redundant dictionaries, for securi ...

Reactive security for multimedia systems

Antonio Romeo

Books, videos, music, still images and any other type of media information, share a number of features that enable their migration from traditional delivery technologies to an all-electronic delivery model. They can easily be digitized, stored, compressed ...

Securing the Internet Routing Infrastructure

Panagiotis Papadimitratos

The unprecedented growth of the Internet over the last years, and the expectation of an even faster increase in the numbers of users and networked systems, resulted in the Internet assuming its position as a mass communication medium. At the same time, the ...

A Decentralized Architecture for Adaptive Media Dissemination

Karl Aberer, Philippe Cudré-Mauroux

P2P content distribution networks have become extremely popular on the Internet. Due to their self-organization properties, they suffer from the lack of control to balance the load among peers for contents of different popularity. In this paper, we define ...

Algorithms for Location-Independent Communication between Mobile Agents

We study the distributed infrastructures required for location-independent communication between mobile agents. These infrastructures are problematic: different applications may have very different patterns of migration and communication, and require diffe ...
