Hydrologic response of an alpine watershed: Application of a meteorological wireless sensor network to understand streamflow generation

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, Daniel Nadeau, Marc Diebold, François Ingelrest, Simone Padoan, Silvia Simoni

A field measurement campaign was conducted from June to October 2009 in a 20 km2 catchment of the Swiss Alps with a wireless network of 12 weather stations and river discharge monitoring. The objective was to investigate the spatial variability of meteorol ...

SensorScope: Application-Specific Sensor Network for Environmental Monitoring

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, François Ingelrest, Olivier Couach

SensorScope is a turnkey solution for environmental monitoring systems, based on a wireless sensor network and resulting from a collaboration between environmental and network researchers. Given the interest in climate change, environmental monitoring is a ...

Potentials of Opportunistic Routing in Energy-Constrained Wireless Sensor Networks

Martin Vetterli, François Ingelrest

The low quality of wireless links leads to perpetual packet losses. While an acknowledgment mechanism is generally used to cope with these losses, multiple retransmissions nevertheless occur. Opportunistic routing limits these retransmissions by taking adv ...

Wireless Sensor Networks for Environmental Monitoring: The SensorScope Experience

Martin Vetterli, Guillermo Barrenetxea Kobas, François Ingelrest

While wireless sensor networks have been extensively studied in the past few years, most results are of theoretical nature and were obtained outside of a practical context. This can be problematic for real applications, especially in the area of environmen ...

Localized Minimum Spanning Tree Based Multicast Routing with Energy-Efficient Guaranteed Delivery in Ad Hoc and Sensor Networks

François Ingelrest

We present a minimum spanning tree based energy aware multicast protocol (MSTEAM), which is a localized geographic multicast routing scheme designed for ad hoc and sensor networks. It uses locally-built minimum spanning trees (MST) as an efficient approxim ...

Maximizing the Delivery of MPR Broadcasting under Realistic Physical Layer Assumptions

François Ingelrest

It is now commonly accepted that the unit disk graph used to model the physical layer in wireless networks does not reflect real radio transmissions, and that a more realistic model should be considered for experimental simulations. Previous work on realis ...

SensorScope: Out-of-the-Box Environmental Monitoring

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, François Ingelrest, Olivier Couach

An important field of application for wireless sensor networks is environmental monitoring. Given the importance of potential climate changes, environmental impact on cities, and pollution, it is an application domain where sensor networks can have great i ...
