针对目前 MP2P 网络因节点频繁移动带来的扰动性，及节点有限的计算、存储能力等限制因素，提出分区管理的灵活策略，将节点按标准进行功能划分，每个子网由超级节点管理。采用部分网络编码技术处理数据，加快数据传输及更替效率。并提出跨子网查询算法加强子网间信息的交互及资源定位。实验结果表明，该策略可以有效地提高资源下载成功率与命中率，减少资源传输延时，改善了 MP2P 网络的内容分发效率，同时也增强了系统的顽健性。%In consideration of the current MP2P network disturbance from frequent location changes of the mobile nodes, the limited computing power and storage capacity, a flexible strategy of partition management by assigning different functions to nodes according to some standards, regarding a subnet as a unit and using super-nodes to manage subnets were proposed. In order to speed up the data transmission and replacement efficiency, data was processed with partial network coding technology. Additionally, a trans-subnet query algorithm was proposed to link subnets, conduct informa-tion exchange between subnets and resource location. Results of the experiment manifested that this strategy can effi-ciently increase the resource download success rate and hit rate, reduce the average delay, improve the content distribu-tion efficiency of MP2P networks, and simultaneously enhance system robustness.
