| 摘 要： | 为了提高P2P网络监控效率,建立P2P网络资源扩散模型讨论P2P资源扩散行为,通过仿真实验分析资源扩散量对资源搜索查全率的影响,发现随着资源扩散,在线资源数量和下线资源数量都以近似对数方式增加,但在资源扩散量很大时,在线资源数量开始下降.另外,随着资源扩散量增大,资源查全率非线性下降,资源热度越高,其查全率越低.上述结论将对P2P网络仿真、建模和协议设计具有一定参考价值.

| Abstract: | To improve monitoring efficiency of P2P network,construct resource disseminating model of P2P network and discuss disseminating behavior of P2P resource.By simulating experiment,analyze the effect of resource's proliferating quantity to recall-ratio of resource searching.Main contribution including,the number of online resource and offline resource both increase as logarithm mode approximately with resource disseminating.However,the number of online resource decreases when resource's proliferating quantity ... |
