D-Trust:A double trust metric based trust model in unstructured P2P network

Based on the widely used flooding Top-k query algorithm of internet,this paper presented an improved threshold Top-k query algorithm of unstructured P2P network by using low boundary of ancestor peers\' local query results in query processing tree as a threshold.

In this paper,by analyzing number of shared resources between the nodes and the network distance between them on the resource classification maintenance and search costs in semantic overlay network,a novel semantic overlay network based on unstructured P2P network is proposed.

Structured P2P networks have attracted more and more attention for their high efficiency and low resource consumption.

Based on structured P2P routing system model and Markov-chain model,this paper presents a quantitative evaluation on routing performance on the network-level of structured P2P network.

Much work has been done on building content-based publish/subscribe systems over structured P2P networks, so that the two technologies can be combined together to better support large-scale and highly dynamic systems.

The structured P2P network such as Tapestry、Pastry、Chord、CAN, are gain quite a lot of attention, because they have many predominances such as the good scalability and the property that can locate the object in finite hops.

Research and application of duplication technology based on unstructured P2P network;

The researches of interest-based driven P2P search method on unstructured P2P network is the most important issue.

Aiming at the problem that locating rare resource is time-consuming with low success rate in unstructured P2P networks,this paper proposes two strategies for rare resource searching:Random Search for Rare resource(RSR) and Flooding and Random Search for Rare resource(FRSR).
