LION：基于位置信息与兴趣偏好的P2P网络区域划分方法

Because of wide application of P2P technology, to construct a reasonable P2P overlay network topology structure becomes one very critical thing. Aim at the problems of structured P2P network without semantic query function, mismatching between physical network and logical network, and scalability and efficiency for unstructured P2P network, this paper proposed a kind of hybrid P2P overlay network. This network makes region division based on location information and interest preference for nodes, solve the problem of mismatching between physical network and logical network, and provide efficient semantic query mechanism, effective shorten the resources positioning time.
