摘要
为有效解决P2P中不同资源的搜索和定位问题,设计了一种基于小世界聚类的资源搜索模型。以小世界模型为理论基础,构建具有局域聚集现象及短的路径的P2P网络模型,按照分级转发方式对资源进行全局搜索。仿真实验证明,这种基于小世界聚类的资源搜索模型具有较高的搜索成功率和较短的平均搜索路径。
A resource search model based on small-world clustering is designed for solving the different resource searching and locating in P2P network effectively. Taking the small-world model as the theoretical basis to construct the P2P network model with local clustering phenomena and short path, the model achieves global searching for resources in the manner of hierarchical forwarding. The simulation experiment shows that the resource search model based on small-world clustering has higher searching success rate and shorter average searching path.
