Tuning Paxos for high-throughput with batching and pipelining

André Schiper, Nuno Filipe de Sousa Santos

Paxos is probably the most popular state machine replication protocol. Two optimizations that can greatly improve its performance are batching and pipelining. Nevertheless, tuning these two optimizations to achieve optimal performance can be challenging, a ...

Introduction to Reliable and Secure Distributed Programming

Rachid Guerraoui, Christian Cachin

This book provides an introduction to distributed programming abstractions and presents the fundamental algorithms that implement them in several distributed en- vironments. The reader is given insight into the important problems of distributed computing a ...

Throughput-Delay Tradeoff for Hierarchical Cooperation in Ad Hoc Wireless Networks

Olivier Lévêque, Ayfer Özgür Aydin

Hierarchical cooperation has recently been shown to achieve better throughput scaling than classical multihop schemes under certain assumptions on the channel model in static wireless networks. However, the end-to-end delay of this scheme turns out to be s ...

Cross-Layer Based Analysis of Multi-Hop Wireless Networks

Tarik Tabet

In this work, we revisit classical packet radio networks with a modern treatment of physical-layer (PHY) procedures, medium-access (MAC) and geographic channel-driven routing protocols. Our network model assumes that nodes are randomly distributed on the p ...

Dual-frequency RF front-ends for GNSS receivers

Frédéric Chastellain

The Global Positioning System (GPS) is a trilateration system which allows to compute the position of a receiver from the time the signals need to propagate from the satellites down to the receiver. Since the Selective Availability (SA) was turned off in 2 ...

Verifiable Network-Performance Measurements

In the current Internet, there is no clean way for affected parties to react to poor forwarding performance: to detect and assess Service Level Agreement (SLA) violations by a contractual partner, a domain must resort to ad-hoc monitoring using probes. Ins ...

Explore the past to improve the Future: How can airlines benefit from historical data?

Niklaus Eggenberg

Airlines schedules are built such as to maximize expected profit. Such schedules turn out to be more sensitive to delay propagation and have lower on-time performance. Robust schedules are thus used instead. In this paper, we compare two different approach ...

Congestion in a competitive world: a study of the impact of competition on airline operations

Niklaus Eggenberg

Air transport is a fast developing area. Airlines compete for a limited resource, namely airport capacity. The consequence is an increase in airport congestion, which generates huge delays that are enhanced due to delay propagation through the whole networ ...
