Broadcast, relay and feedback in Gaussian channels

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 ...

The scaling of the broadcast capacity of extended wireless networks with cooperative relays

Michael Christoph Gastpar

We study the scaling of the broadcast capacity for a network with a single source and f(N) cooperative relays where N is the number of destinations and f(.) is an increasing function. We consider random extended networks (the network area goes to infinity ...

Systems and methods for broadcasting information additive codes

Mohammad Amin Shokrollahi

A broadcasting system for communicating data to multiple receivers using information additive code includes one or more information additive code transmitters and one or more information additive code receivers. Each of the information additive code transm ...

Audio Coding Based on Long Temporal Contexts

Petr Motlicek, Hynek Hermansky

We describe novel audio coding technique designed to be utilized at medium bit-rates. Unlike classical state-of-the-art audio coders that are based on short-term spectra, our approach uses relatively long temporal segments of audio signal in critical-band- ...

Precoding for broadcasting with linear network codes

Ali H. Sayed

A technique based on linear precoding is introduced for broadcasting on linear networks. The precoding allows the different message components of a broadcast message to be separated and decoded at the desired sink nodes, thus providing a systematic design ...

Low-complexity energy-efficient broadcasting in wireless ad-hoc networks using network coding

Jean-Yves Le Boudec, Christina Fragouli, Jörg Widmer

Energy efficiency, i.e., the amount of battery energy consumed to transmit bits across a wireless link, is a critical design parameter for wireless ad-hoc networks. We examine the problem of broadcasting information to all nodes in an ad-hoc network, when ...

Energy-efficient Broadcasting in All-wireless Networks

Jean-Pierre Hubaux, Christian Enz, Mario Cagalj

In all-wireless networks, minimizing energy consumption is crucial as in most cases the nodes are battery-operated. We focus on the problem of power-optimal broadcast, for which it is well known that the broadcast nature of radio transmissions can be explo ...

Processor Enhancements for Media Streaming Applications

Pierre Vandergheynst, Sébastien Bilavarn

The development of more processing demanding applications on the Internet (video broadcasting) on one hand and the popularity of recent devices at the user level (digital cameras, wireless videophones, ...) on the other hand introduce challenges at several ...

Broadcasting Messages in Fault-Tolerant Distributed Systems: the benefit of handling input-triggered and output-triggered suspicions differently

André Schiper, Xavier Défago

This paper investigates the two main and seemingly antagonistic approaches to broadcasting messages in fault-tolerant distributed systems: the approach based on Reliable Broadcast, and the one based on View Synchronous Communication (or VSC for short). We ...

Minimum-energy broadcast in all-wireless networks: NP-completeness and distribution issues

Jean-Pierre Hubaux, Christian Enz, Mario Cagalj

In all-wireless networks a crucial problem is to minimize energy consumption, as in most cases the nodes are battery-operated. We focus on the problem of power-optimal broadcast, for which it is well known that the broadcast nature of the radio transmissio ...
