Distributed data aggregation is an important task, allowing the decentralized determination
of meaningful global properties, which can then be used to direct the execution of other …

Uncertain data have already widely existed in many practical applications recently, such as
sensor networks, RFID networks, location-based services, and mobile object management …

Progress of research efforts in a novel technology is contingent on having a rigorous
organization of its knowledge domain and a comprehensive understanding of all the …

Nowadays, there is an increasing demand to monitor, analyze, and control large scale
distributed systems. Events detected during monitoring are temporally correlated, which is …

This paper exploits the tradeoff between data qual-ity and energy consumption to extend the
lifetime of wireless sensor networks. We consider the applications that require some …

Top-k monitoring is important to many wireless sensor applications. This paper exploits the
semantics of top-k query and proposes an energy-efficient monitoring approach called FILA …

We are inevitably moving into a realm where small and inexpensive wireless devices would
be seamlessly embedded in the physical world and form a wireless sensor network in order …

In this paper we introduce the idea of snapshot queries for energy efficient data acquisition
in sensor networks. Network nodes generate models of their surrounding environment that …

The use of the Lattice monitoring framework as a fundamental part of a overlay management
system for virtual networks is presented. Lattice has been specially designed for monitoring …

Despite the increasing use of the wireless sensor network in many applications, especially
critical ones, exploiting the full potential of this network is very difficult due to many …
