The Beauty of the Commons: Optimal Load Sharing by Base Station Hopping in Wireless Sensor Networks

Martin Vetterli, Patrick Thiran, Guillermo Barrenetxea Kobas, François Ingelrest, Runwei Zhang

In wireless sensor networks (WSNs), the base station (BS) is a critical sensor node whose failure causes severe data losses. Deploying multiple fixed BSs improves the robustness, yet requires all BSs to be installed with large batteries and large energy-ha ...

ns-level time transfer over a microwave link using the PTP-WR protocol

Pierre-André Farine, Cyril Botteron, Jean-Pierre Aubry, Mathieu Paul Joseph Carlos Rico

Today it is possible to achieve sub-ns level time synchronization on a wireline network while only us-level synchronization can be achieved on a wireless (microwave) link. In this paper we will, first, study the performances of different time synchronizati ...

Colour simplex coding for brillouin distributed sensors

Luc Thévenaz, Marcelo Alfonso Soto Hernandez

The possibility to customize Simplex coding for long range Brillouin Optical Time Domain Analysis is demonstrated by “colouring” the sequences in the frequency domain. The coding gain is identical to the traditional intensity-modulated Simplex code, though ...

Wireless GPS-based phase-locked synchronization system for outdoor environment

Alexander Bahr, Frédéric Meyer, Thomas Lochmatter

Synchronization of data coming from different sources is of high importance in biomechanics to ensure reliable analyses. This synchronization can either be performed through hardware to obtain perfect matching of data, or post-processed digitally. Hardware ...
