基于信任管理的对等网络路由选择

在对等网络中每个节点都充当了路由的作用，在搜索某文件时，正确地选择转发节点，可提高搜索文件的效率。构建了基于信任的动态拓扑模型，给出了节点信任度评估的方法；提出了用加密发送消息的方法，确定故障节点；通过设定CPU的响应时间阈值，解决高可信节点因被链接过多而导致的节点拥塞，避免对高可信节点的完全依赖；设计了基于信任的节点链接更新算法，提高了网络性能。通过仿真实验验证了该方法的正确性。

Routing of P2P based on trust management

Each node in P2P networks acts as a router;therefore,selecting appropriate note to store-and-forward packets in searching a certain file can improve the efficiency.The authors constructed a dynamic topology model based on trusting scheme,gave the approaches to assess node reliability-rate and detected fault nodes with encrypted messages sending.The congestion of nodes caused by too many links of high-reliability-rate nodes could be avoided in terms of setting response threshold of CPU's response time.To imp...
