Valuable Detours: Least-Cost Anypath Routing

Martin Vetterli, Matthias Grossglauser, 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. 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

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

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

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

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 ...

SensorScope: Experiences with a Wireless Building Monitoring Sensor Network

Martin Vetterli, Henri Julien Dubois-Ferrière, 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 ...
