Valuable Detours: Least-Cost Anypath Routing

Henri Julien Dubois-Ferrière, Martin Vetterli, Matthias Grossglauser

In many networks, it is less costly to transmit a packet to any node in a set of neighbors than to one specific neighbor. This observation was previously exploited by opportunistic routing protocols by using single-path routing metrics to assign to each no ...

A Weather Station for SensorScope

Roger Meier, Henri Julien Dubois-Ferrière, Guillermo Barrenetxea Kobas

The SensorScope project is a collaboration between environmental scientists and hardware/software engineers at EPFL. It will consist of two large-scale outdoor sensor networking deployments, the first on the EPFL campus, and the second on an alpine glacier ...

TinyNode: A Comprehensive Platform for Wireless Sensor Network Applications

Roger Meier, Henri Julien Dubois-Ferrière, Laurent Fabre, Pierre Métrailler

We introduce the TinyNode platform for wireless sensor networks. Supporting both research and industrial deployments, the platform offers communication ranges that exceed current platforms by a factor of 3 to 5, while consuming similar energy. It comes wit ...

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 ...

Packet Combining in Sensor Networks

Henri Julien Dubois-Ferrière, Martin Vetterli

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 ...

SensorScope: Experiences with a Wireless Building Monitoring Sensor Network

Henri Julien Dubois-Ferrière, Martin Vetterli, Thomas Schmid

This paper reports on our experience with the implementation, deployment, and operation of SensorScope, an indoor environmental monitoring network. Nodes run on standard TinyOS components and use B-MAC for the MAC layer implementation. The main component o ...
