The multi-commodity flow problem is a classical combinatorial optimization problem that addresses a number of practically important issues of congestion and bandwidth management in connection-oriented network architectures. We consider solutions for distributed multi-commodity flow problems,...
The paper considers broadcasting in radio networks, modeled as unit disk graphs (UDG). Such networks occur in wireless communication between sites (e.g., stations or sensors) situated in a terrain. Network stations are represented by points in the Euclidean plane, where a station is connected to...
Data replication is a key technique for ensuring data availability. Traditionally, researchers have focused on the availability of individual objects, even though user-level tasks (called operations) typically request multiple objects. Our recent experimental study has shown that the assignment...
