Diffusion LMS strategies for parameter estimation over fading wireless channels

We propose a modified diffusion strategy for parameter estimation in sensor networks where nodes exchange information over fading wireless channels. We show that the effect of fading can be mitigated by incorporating local equalization coefficients into th ...

A High-Throughput Byzantine Fault-Tolerant Protocol

Nikola Knezevic

State-machine replication (SMR) is a software technique for tolerating failures and for providing high availability in large-scale systems, through the use of commodity hardware. A replicated state-machine comprises a number of replicas, each of which runs ...

Distributed throughput optimization over P2P mesh networks using diffusion adaptation

Ali H. Sayed

This work develops a decentralized adaptive strategy for throughput maximization over peer-to-peer (P2P) networks. The adaptive strategy can cope with changing network topologies, is robust to network disruptions, and does not rely on central processors. T ...

On the effects of topology and node distribution on learning over complex adaptive networks

Ali H. Sayed

Adaptive networks consist of a collection of nodes with adaptation and learning abilities. The nodes interact with each other on a local level and diffuse information across the network through their collaborations, as dictated by the network topology and ...

Self-Adaptive Attractor-Shaping for Oscillators Networks

Max-Olivier Hongler, Philippe Blanchard, Julio Rodriguez

We consider a network of N coupled limit cycle oscillators, each having a set of control parameters Λ_k, k = 1, . . . , N, that controls the frequency and the geometry of the limit cycle. We implement a self-adaptive mechanism that drives the local systems ...

Progressive quantization in distributed average consensus

Pascal Frossard, Effrosyni Kokiopoulou

We consider the problem of distributed average consensus in a sensor network where sensors exchange quantized information with their neighbors. In particular, we exploit the increasing correlation between the exchanged values throughout the iterations of t ...

Throughput Optimal Total Order Broadcast for Cluster Environments

Rachid Guerraoui, Bastian Pochon, Ron Levy

Total order broadcast is a fundamental communication primitive that plays a central role in bringing cheap software-based high availability to a wide range of services. This paper studies the practical performance of such a primitive on a cluster of homoge ...

Network Tomography on Correlated Links

Patrick Thiran, Denisa Gabriela Ghita

Network tomography establishes linear relationships between the characteristics of individual links and those of end-to-end paths. It has been proved that these relationships can be used to infer the characteristics of links from end-to-end measurements, p ...

Stretching BFT

Rachid Guerraoui, Marko Vukolic, Nikola Knezevic

State-of-the-art BFT protocols remain far from the maximum theoretical throughput. Based on exhaustive eval- uation and monitoring of existing BFT protocols, we highlight few impediments to their scaling. These include the use of IP multicast, the presence ...

Information-theoretic secrecy for wireless networks

Etienne Perron

The aim of information-theoretic secrecy is to ensure that an eavesdropper who listens to the wireless transmission of a message can only collect an arbitrarily small number of information bits about this message. In contrast to cryptography, there are no ...
