| 摘 要： | 提出一种基于社会特性的P2P资源查找策略。将具有类似兴趣的节点组织成多个兴趣簇,形成一个多簇相互交叠的重叠网络拓 扑。节点通过相似度比较,选择与自己兴趣度最相似的候选节点建立邻居关系,结合带偏向的随机走动策略和跨簇节点广度优先搜索策略,进行资源查找。实验结果表明,该策略的查找成功率较高。

| Abstract: | This paper proposes a Peer-to-Peer(P2P) resource searching strategy based on social characteristics.It clusters the nodes which hold similar interests into a specific cluster,result into a multi-cluster interconnected overlay topology.Every node select most similar candidate node as its neighbors.When confronts with resource searching,node combines biased random walk with breadth first search strategy to locate the searching object.Experimental results indicate that the strategy is a high efficiency searching strategy. |
