On Broadcast with a Common Message over Networks

Satish Babu Korada, Dinkar Vasudevan

We consider the following communication problem over a directed graph. A source node wants to transmit a common message to a set of receiver nodes along with a private message to each of the receivers. We show a class of networks for which the achievable r ...

Brillouin-Based Distributed Temperature Sensor Employing Pulse Coding

Marcelo Alfonso Soto Hernandez

A distributed temperature sensor based on spontaneous Brillouin scattering and employing optical pulse coding has been implemented and characterized using a direct-detection receiver. The signal-to-noise ratio (SNR) enhancement provided by coding is analyz ...

Even Small Birds are Unique: Population Protocols with Identifiers

Rachid Guerraoui, Eric Ruppert

Although much research has been devoted to designing and experimenting on ad hoc networks of tiny devices, very little has focussed on devising theoretical models to capture the inherent power and limitations of such networks. A notable exception is the po ...

Space-time coding in MISO-OFDM systems with implementation impairments

Ali H. Sayed

Implementation of OFDM-based systems suffers from in-phase and quadrature-phase (IQ) imbalances in the front-end analog processing. The resulting distortion due to IQ imbalances can limit the achievable operating SNR at the receiver, especially when space- ...

SOWER: Self-Organizing Wireless Network for Messaging

Jean-Pierre Hubaux, Mark Felegyhazi, Srdan Capkun

Short Message Service (SMS) has become extremely popular in many countries, and represents a multi-billion dollars market. Yet many consumers consider that the price charged by the cellular network operators is too high. In this paper, we explain that ther ...

Reliability and latency in binary communication

Emre Telatar, Aslan Tchamkerten

The transmission of one of two messages over a binary symmetric channels with perfect and instantaneous feedback is considered. We study the situation where transmitter and receiver want to communicated reliably and quickly. We propose a simple decoding ru ...

An Efficient Universal Construction for Message-Passing Systems

Rachid Guerraoui, Bastian Pochon, Partha Dutta

A universal construction is an algorithm that transforms any object with a sequential specification into a wait-free and linearizable implementation of that object. This paper presents a novel universal construction algorithm for a message-passing system w ...

Quantifying the Performance Differences Between PVM and TreadMarks

Willy Zwaenepoel, Sandhya Dwarkadas

We compare two systems for parallel programming on networks of workstations: Parallel Virtual Machine (PVM) a message passing system, and TreadMarks, a software distributed shared memory (DSM) system. We present results for eight applications that were imp ...
