Abstract :
The characteristics, such as non-centralized structure, good autonomy and fault tolerance and so on, cause peer-to-peer network to be an effective resources sharing model on the Internet. However, the resource-located problem and the free-riding phenomenon of P2P are the most primary challenges. In this paper, semantic similarity, trust degree and active strength of the peer are fully considered, what is more, a construction method and a dynamic adjustment mechanism of the DVC (Dynamic Virtual semantic Community) will be proposed, which can not only offer a semantic-based structural organization form for P2P, enhance the accuracy of the resources localization, but also reduce and eliminate the free-riders simultaneously as well. The purpose is to make the P2P DVCs have the dynamic evolution, a better robustness and usability. The experiment shows that the DVCs can be formed with high efficiency and accuracy in P2P.
