Distributed Spectrum Assignment for Home WLANs

Patrick Thiran, Ruben Merz, Julien Pierre Sacha Herzen

We consider the problem of jointly allocating chan- nel center frequencies and bandwidths for IEEE 802.11 wireless LANs (WLANs). The bandwidth used on a link affects sig- nificantly both the capacity experienced on this link and the interference produced o ...

On the Necessity of Traffic Shaping for PMU Measurement Data Streams

Jean-Yves Le Boudec, Dan-Cristian Tomozei, Peng Gao, Miroslav Popovic

We study the communication network of an on-campus active distribution network (ADN) that comprises phasor measurement units (PMUs) connected to medium-voltage transformers. Within stringent time delays and with minimal loss the PMUs periodically transfer ...

Insomnia in the Access (or How to Curb Access Network Related Energy Consumption)

Dejan Kostic, Marco Canini, Alberto López

Access networks include modems, home gateways, and DSL Access Multiplexers (DSLAMs), and are responsible for 70-80% of total network-based energy consumption. In this paper, we take an in-depth look at the problem of greening access networks, identify root ...

A New Planar Antenna Element For Ka-Band Applications

Juan Ramon Mosig, Jean-François Zürcher, Rafal Glogowski

One of the most promising bands for long-range radiocommunications is the Ka-band (25-40 GHz). This is due to the existence of a natural radio transmission window around 30 GHz. Both terrestrial and satellite transmission systems are planned on this freque ...

Glass transition associated with the jamming of vibrated granular matter

Gérard Gremaud, Daniele Mari, Alessandro Luigi Sellerio

We investigate a vibrated granular system composed of millimeter-size glass beads. When the system is submitted to a perturbation with decreasing intensity, below the fluidization limit, it evolves in a way similar to glass-forming liquids until it reaches ...
