Opportunistic Data Collection in Sparse Wireless Sensor Networks

Jorge Miguel Dias Almeida Rodrigues Soares

Opportunistic wireless sensor networks (WSNs) have recently been proposed as solutions for many remote monitoring problems. Many such problems, including environmental monitoring, involve large deployment scenarios with lower-than-average node density, as ...

A Fault-Tolerant Token-Based Atomic Broadcast Algorithm

André Schiper, Nils Richard Ekwall

Many atomic broadcast algorithms have been published in the last 20 years. Token-based algorithms represent a large class of these algorithms. Interestingly, all the token-based atomic broadcast algorithms rely on a group membership service and none of the ...

Swift Algorithms for Repeated Consensus

André Schiper, Martin Hutle, Fatemeh Borran, Nuno Filipe de Sousa Santos

We introduce the notion of a swift algorithm. Informally, an algorithm that solves the repeated consensus is swift if, in a partial synchronous run of this algorithm, eventually no timeout expires, i.e., the algorithm execution proceeds with the actual spe ...

A Subband Adaptive Iterative Shrinkage/Thresholding Algorithm

Ilker Bayram

We investigate a subband adaptive version of the popular iterative shrinkage/thresholding algorithm that takes different update steps and thresholds for each subband. In particular, we provide a condition that ensures convergence and discuss why making the ...

Nonlinear Average Consensus

Martin Hasler, Leonidas Georgopoulos

We present an algorithm for nonlinear consensus in complex networks. Our motivation draws from analysis on the algorithm based on a weighted linear update protocol. Comparison of the asymptotic with early convergence rate encourages an alternative algorith ...

Estimation of modelling errors in structural system identification

Ian Smith, James-Alexandre Goulet

This paper presents a method for measurement-system design through criteria related to model based structural identification. Using a multi-model approach and results from previous research carried out at EPFL, an improved algorithm is proposed. The algori ...

Diffusion least-mean squares with adaptive combiners

Ali H. Sayed

This paper presents an efficient adaptive combination strategy for diffusion algorithms over adaptive networks in order to improve the robustness against the spatial variation of SNR over the network. The diffusion least-mean square (LMS) algorithm with th ...

Testing a reliable in-vehicle navigation algorithm in the field

The results of a field experiment carried out to assess the accuracy and efficiency of a new in-vehicle navigation algorithm, whose aim is to incorporate and consider travel time reliability and route the guided vehicle along uncongested roads, in the abse ...

Multimodal Speaker Localization from Omnidirectional Videos

Jean-Philippe Thiran, Mihai Gurban, Pascal Reuse

The use of omnidirectional cameras for videoconferencing promises to simplify the hardware setup necessary for large groups of participants. We investigate the use of a multimodal speaker detection algorithm on audio-visual sequences captured with such a c ...
