摘　　要：提出一种基于网格坐标自治域的移动P2P网络拓扑构造方法,通过节点映射机制保证物理网络中距离较近的节点在覆盖网上也相近,从而构建具有拓扑匹配的移动P2P网络。针对该拓扑结构提出了基于分层索引节点的资源查找策略。仿真实验结果表明,该策略能够有效提高资源查找成功率,降低资源查找平均路径长度,获得了较好的查询性能。This paper proposed a new method of topology construction based on grid coordinates autonomous domain. In order to build a topology matching overlay networks, this paper presented the node mapping mechanism to guarantee that the nodes adjacent to each other in physical network were also neighbors in overlay network. In addition, it proposed the resource searching strategy based on the hierarchical index according to the proposed architecture. The simulation results show that strategy can effectively improve the success rate of searching and reduce the average path length.
