中文摘要：

为了符合实际P2P网络中的节点异质性的情形并支持语义查询,在分析自组织网络模型和双层结构化P2P网络模型以后,提出了一种基于移动代理的结构化P2P网络模型AS-P2P.理论分析和模拟实验结果表明,在加入了移动代理转移资源索引和使用双层结构化P2P网络区别节点能力以后,AS-P2P更加适应动态网络,并具有平均查找长度短,超级节点上负载均衡和资源索引分类等优点.

英文摘要：

For a better support for differences among nodes of real P2P networks and semantic search,after analyzing the self-organized network and structured P2P network,a mobile agent based structured P2P network （AS-P2P） is proposed.The theory analysis and experiments simulation show that with the help of mobile agent and usage of two layer structure model,AS-P2P gets the advantages such as adapting to the dynamic of the network quickly,shorter search length,resource index load balance and classification on super peer.
