| 摘 要： | 无结构P2P网络中某些共享资源高的节点容易出现网络阻塞和瓶颈问题.针对此问题引入小世界思想,建立具有小世界特征的网络模型.实验证明该模型不仅能阻止P2P网络中形成星形结构,还达到网络负载平衡和避免网络拥塞,并将用户获取的服务与其提供的共享资源联系起来,体现一定的公平性.

| Abstract: | Certain high sharing nodes in unstructured P2P networks are vulnerable to counter congestion and bottlenecks.We propose a small world model according to the user's sharing resource and network topology in unstructured P2P network.Experiments show that it can prevent the formation of star subnet in P2P network,and can exhibit some balance for all users by assigning the user server according to their shared resource. |
