In this paper, a social network model based on real social relationships, referred as Relation Grid, is proposed. Relation grid is isomorphic to the actual social network; hence it...
According to the special features of the dynamic heterogeneous grid environment, a loose-coupled and scalable resource model is described by a hybrid multi-level tree reflecting a...
The goal of a Public-Key-Infrastructure (PKI) is to prove whether a cryptographic public key is authentic for a certain user. This information is crucial for the reliability of as...
To exploit the similarity information hidden in the hyperlink structure of the web, this paper introduces algorithms scalable to graphs with billions of vertices on a distributed ...
This paper shows how to build and maintain a distributed heap which we call SHELL. In contrast to standard heaps, our heap is oblivious in the sense that its structure only depends...
