Methods for hardware reduction and overall performance improvement in communication system

Giovanni De Micheli

The aim of the present invention is a method to achieve the customization of the communication network of a multicore communication system. This goal is achieved thanks to a method to design a multicore communication system, said communication system compr ...

Raptor Network Video Coding

Pascal Frossard, Nikolaos Thomos

In this paper, we consider the problem of streaming video information on lossy packet networks with path and source diversity, such as wireless mesh networks or more generally overlay architectures. We propose to distribute the video information between se ...

Broadcast, relay and feedback in Gaussian channels

Sibi Raj Bhaskaran Pillai

Network information theory explores the fundamental data transport limits over communication networks. Broadcasting and relaying are two natural models arising in communication contexts where multiple users share a common communication medium. Number of re ...

Network Monitoring: it depends on your points of view

Christina Fragouli, Suhas Diggavi

End-to-end active network monitoring infers network characteristics by sending and collecting probe packets from the network edge, while probes traverse the network through multicast trees or a mesh of unicast paths. Most reported methods consider given so ...

On feedback for network coding

Christina Fragouli

In this paper we examine possible ways that feedback can be used, in the context of systems with network coding capabilities. We illustrate, through a number of simple examples, that use of feedback can be employed for parameter adaptation to satisfy QoS r ...

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 ...

Rateless coding with partial CSI at the decoder

Michael Christoph Gastpar

A channel model for channels with unknown state and partial state information available causally at the decoder is proposed. The model is based on arbitrarily varying channels (AVCs), and the partial state information is characterized by allowing the decod ...

Efficient and Adjustable Recipient Anonymity in Mobile Ad Hoc Networks

Panagiotis Papadimitratos, Reza Shokri, Amir Nayyeri

The privacy of users of mobile devices has been at stake, with emerging systems based on the mobile ad hoc networking technology raising additional concerns. The establishment of a connection between two nodes could readily reveal information to an eavesdr ...

Network Correlated Data Gathering with Explicit Communication: NP-Completeness and Algorithms

Martin Vetterli, Razvan Cristescu

We consider the problem of correlated data gathering by a network with a sink node and a tree based communication structure, where the goal is to minimize the total trans- mission cost of transporting the information collected by the nodes, to the sink nod ...

Node Cooperation in Hybrid Ad hoc Networks

Jean-Pierre Hubaux, Naouel Ben Salem, Levente Buttyan

A hybrid ad hoc network is a structure-based network that is extended using multi-hop communications. Indeed, in this kind of network, the existence of a communication link between the mobile station and the base station is not required: A mobile station t ...
