The tremendous growth of public interest in Peer-to-Peer (P2P) networks in recent years has
initiated a lot of research work on how to design efficient overlay structures for P2P systems …

Several algorithms have been recently developed for distributed data clustering, which are
applied when data cannot be concentrated on a single machine, for instance because of …

Security concerns currently deter or prohibit many organisations from leveraging the benefits
of the grid. When sensitive data is placed under the control of third-party infrastructure it is …

We present a new model and a partial solution to the problem of semantic routing in peer-to-
peer networks. When a peer receives a query, an attempt to solve the query by using both …

This paper presents a new balanced, distributed data structure for storing data with
multidimensional keys in a peer-to-peer network. It supports range queries as well as single …

A growing number of applications in distributed environment involve very large data sets that
are inherently distributed among a large number of autonomous sources over a network …

Sensor networks are usually composed by spatially distributed devices able to monitor
physical or environmental conditions (pressure, temperature, motion, etc.). This kind of …

Query processing on mobile sensor networks requires efficient indexing and partitioning of
the data space to support efficient routing as the network scales up. Building an index …

Network intrusion detection is a key security issue that can be tackled by means of different
approaches. This paper describes a novel methodology for network attack detection based …

Large scale wireless ad-hoc networks of computers, sensors, PDAs etc.(ie nodes) are
revolutionizing connectivity and leading to a paradigm shift from centralized systems to …
