Normalisation of Histogrammed List Mode Data

Many PET scanners nowadays have the possibility to record event-by-event information, known as list mode data. This has the advantage of keeping the data in the highest possible resolution (both temporal and spatial). In most cases, list mode data are then ...

Energy Efficiency in Wireless Sensor Networks: A Utility-Based Architecture

Ioannis Alagiannis, Manoussos Gavriil Athanassoulis

Wireless Sensor Networks (WSN) comprise a fast developing research area with a vast spectrum of applications. A WSN design is influenced by many factors such as transmission errors, network topology and power consumption. Consequently, developing a WSN app ...

MobiRoute: Routing towards a Mobile Sink for Improving Lifetime in Sensor Networks

Jean-Pierre Hubaux, Matthias Grossglauser, Jun Luo, Jacques Panchard

Improving network lifetime is an important issue involved in every aspect of the design and deployment of wireless sensor networks. There is a recent research trend of studying the application of a mobile sink to transport (rather than let the sensor nodes ...

On the optimal density for real-time data gathering of spatio-temporal processes in sensor networks

Martin Vetterli, Razvan Cristescu

We consider sensor networks that measure spatio-temporal correlated processes. An important task in such settings is the reconstruction at a certain node, called the sink, of the data at all points of the field. We consider scenarios where data is time cri ...
