Distributed MMSE Relay Strategies for Wireless Sensor Networks

Ali H. Sayed

A fundamental task in a wireless sensor network is to broadcast some measured data from an origin sensor to a destination sensor. Since the sensors are typically small, power limited, and low cost, they are only able to broadcast low-power signals. As a re ...

Anypath routing

Henri Julien Dubois-Ferrière

In many networks, it is less costly to transmit a packet to any node in a set of neighbors than to one specific neighbor. A well-known instance is with unreliable wireless links, where the probability that at least one node out ofnreceives a packet increas ...

MobiRoute: Routing towards a Mobile Sink for Improving Lifetime in Sensor Networks

Jean-Pierre Hubaux, Matthias Grossglauser, Jun Luo, Jacques Panchard

Improving network lifetime is an important issue involved in every aspect of the design and deployment of wireless sensor networks. There is a recent research trend of studying the application of a mobile sink to transport (rather than let the sensor nodes ...

Switch Detection in Genetic Regulatory Networks

Giancarlo Ferrari Trecate

This paper considers piecewise affine models of genetic regulatory networks and focuses on the problem of detecting switches among different modes of operation in gene expression data. This task constitutes the first step of a procedure for the complete id ...

Network coding for efficient communication in extreme networks

Jean-Yves Le Boudec, Jörg Widmer

Some forms of ad-hoc networks need to operate in extremely performance- challenged environments where end-to-end connectivity is rare. Such environments can be found for example in very sparse mobile networks where nodes ”meet” only occasionally and are ab ...

Packet Combining in Sensor Networks

Martin Vetterli, Henri Julien Dubois-Ferrière

This paper presents the Simple Packet Combining (SPaC) error-correction scheme for wireless sensor networks. Nodes buffer corrupt packets, and when two or more corrupt versions of a packet have been received, a packet combining procedure attempts to recove ...

Energy efficient medium access control for wireless sensor networks

A wireless sensor network designates a system composed of numerous sensor nodes distributed over an area in order to collect information. The sensor nodes communicate wirelessly with each other in order to self-organize into a multi-hop network, collaborat ...

Joint Synchronization, Routing and Energy Saving in Multi-hop Hybrid Networks

Jean-Pierre Hubaux, Dan Jurca

Multi-hop hybrid networks can help providing both high bandwidth and broad coverage for wireless data networks. We focus on CSMA/CA-based networks and take IEEE 802.11 as a concrete example. We show that the three fundamental operations of synchronization, ...

Tree-Based Pursuit

Pascal Frossard, Pierre Vandergheynst, Philippe Jost

Building good sparse approximations of functions is one of the major themes in approximation theory. When applied to signals, images or any kind of data, it allows to deal with basic building blocks that essentially synthesize all the information at hand. ...
