Proactive Uniform Data Replication by Density Estimation in Apollonian P2P Networksed at the cost of maintaining a random apollonian overlay. Thanks to the small world and scale free properties of the random apollonian P2P overlay, the search efficiency of the space filling tree algorithm we propose has comparable performances with the classical flooding algorithm on a random network.

Designing, Specifying and Querying Metadata for Virtual Data Integration Systemsrs that is provably correct for monotone relational global queries. For query answering, evaluation engines for answer set programs on relational databases are used. The programs declaratively specify the legal instances of the integration system.

Pace: Privacy-Protection for Access Control Enforcement in P2P Networkscable to networks consisting entirely of untrusted nodes. The main feature of our protocol is that it protects both sensitive permissions and sensitive policies, and does not rely on any centralized authority. We analyze the efficiency (computational effort and communication overhead) as well as the security of our protocol.

We provide an experimental evaluation showing that our approach performs efficiently and outperforms existing techniques.
