In order to process continuous queries over Wireless Sensor Networks (WSNs), sensors are
typically organized in a Query Routing Tree (denoted as T) that provides each sensor with a …

Over the years, online processing of data has become more important. In inventory
management, monitoring and financial applications data is generated in streams that are …

With more and more real deployments of wireless sensor network applications, we envision
that their success is nonetheless determined by whether the sensor networks can provide a …

This work addresses the problem of efficient distributed detection of predicates capturing the
motion trends of mobile objects evaluated with respect to a (boundary of a) polygonal …

Rés umé Dans un papier précédent [Der90], nous avons proposé un détecteur de points
anguleux se basant sur une analyse multi échelle et permettant une localisation exacte de …

Computing is currently getting at the same time incredibly in the small with sensors/actuators
embedded in our every-day objects and also greatly in the large with data and ser-vice …

To achieve scalability, energy-efficiency, and timeliness, wireless sensor network
deployments increasingly employ in-network processing. In this paper, we identify singlehop …

Many applications operate in heterogeneous wireless sensor networks, which represent a
challenging programming environment due to the wide range of device capabilities. Servilla …

Network protocols are typically designed and tested individually. In practice, however,
applications use multiple protocols concurrently. This discrepancy can lead to failures from …

Recent technological advances have reduced the complexity and cost of developing sensor
networks for remote environmental monitoring. However, the challenges of acquiring …
