摘要:
非结构化P2P网络模型Gnutella,由于采取简单洪泛算法,随着网络规模的增大网络流量呈指数增长,限制了网络的规模。提出一种在Gnutella基础上的概率转发模型(probability routing model based on Gnutella,PRG)。PRG模型是在queryhit消息中添加额外的节点信息来构建概率转发表,系统中的节点根据转发表进行搜索并非简单洪泛。仿真结果表明该模型可以减少网络流量,提高查询效率,并在一定程度上提高查询命中率。
Abstract:
When there are more and more nodes in the Gnutella,flow in network is in exponential growth and so has confined the scale of network because it uses flooding.This paper has presented a model of probability routing based on Gnutella(PRG).It creates a propability routing table by the extra information about corresponding node from the message of queryhit. Simulation results show this model can reduce the flow in the network and improve the efficiency ofquery effectively.
