Peer-to-Peer (P2P) networks have proven to be an efficient and successful mechanism for file sharing over the Internet. However, current P2P protocols have long worst case query...
Many scientific applications need to stage large volumes of files from one set of machines to another set of machines in a wide-area network. Efficient execution of such data t...
Intuitively, a signed graph is a graph in which every edge is labeled with a + or − sign. For each edge, its sign represents the mode of the relationship between the vertices it...
The scalability properties of DHT based overlay networks is considered satisfactory. However, in large scale systems this might still cause a problem since they have a logarithmic...
Tracing resource usage by Grid users is of utmost importance — especially in the context of large-scale scientific collaborations such as within the High Energy Physics (HEP) c...
