Survey on resource discover methods in unstructured P2P network
无结构对等中网络资源发现方法研究的最新进展

Many search methods have been presented to avoid the large volume of unnecessary traffic incurred by the flooding-based search in unstructured P2P systems.According to the features of presented search methods,roughly divided into four categories: forwarding-base methods;cache-based methods;methods based on replication of both query and data;methods based on topology optimization.After analyzed the merits and shortcomings of all kinds of methods,the paper pointed out that any kind of search methods could only optimize a certain aspect of performance.If integrated several kinds of search algorithms smoothly,the optimization performance will be better.At last,gave some important conclusions.
