he Optimize and Simulation of Resource Search Algorithm Based on Small-World Theory in P2P
P2P资源搜索研究是P2P领域一个重要部分。本文结合小世界理论的研究，对传统资源搜索算法进行了优化，提出了一种新的资源搜索算法。该算法将无组织的P2P系统中根据带宽等其他因素将节点组织化，达到组织化的P2P系统的性能，同时具有非组织P2P系统的优点。我们借鉴small-world理论的研究成果，对随机化的P2P系统进行处理，使网络的逻辑拓扑结构达到一定的特性，使之达到small-world理论模型要求，提高整个系统的性能。仿真结果表明，与传统资源搜索算法相比，这种新的算法具有在搜索性和扩展性具有一定程度的改进。
he research in P2P resource search is an important part in P2P field. We propose a new resource search algorithm base on the classical algorithm through a combination of small-world theory. According to bandwidth or other factor, we make some structural change in the unstructured P2P system, so it can reach the property of structural system., and it have the advantage of the unstructured P2P system. We use small-world theory to deal the randomly P2P system, and it makes the logical topology of the network appearing some special characters, so it can improve the performance of the system. In the end, the simulate result show that the new algorithm perform well in resource search and extensibility.
