A Practically Implementable and Tractable Delegation Logic
We address the goal of making Delegation Logic (DL) into a practically implementable and tractable trustmanagement system. DL [22] is a logic-based knowledge representation (i.e.,...

Cluster-Based Intelligent Searching in Unstructured Peer-to-Peer Networks
Existing cluster-based searching schemes in unstructured peer-to-peer (P2P) networks employ flooding/random forwarding on connected dominating sets (CDS) of networks. There exist...
