In this paper we model and study the performance of peer-to-peer (P2P) file sharing systems in terms of their `service capacity'. We identify two regimes of interest: the tra...
The open-source rsync utility reduces the time and bandwidth required to update a file across a network. Rsync uses an interactive protocol that detects changes in a file and se...
In this paper, we study query processing in a distributed text database. The novelty is a real distributed architecture implementation that offers concurrent query service. The di...

In this paper we show the power of sampling techniques in designing efficient distributed algorithms. In particular, we show that using sampling techniques, on some networks, sele...
In a mobile computing system, users carrying portable devices can access database services from any location without requiring a fixed position in the networking environment. Some ...
