摘　　要：对等网络是一种分布式网络技术,如何提高文件搜索效率是对等网络发展的关键所在,支持语义查询是更好提高搜索效率的途径之一。SWLDRM是Chord的改进模型,它使用DHT算法在节点上分配文件,适合精确查找,不支持语义查询。以SWLDRM为基础,通过语义空间将节点根据存储数据对象的兴趣聚集,构建语义层次分布式网络路由模型SLDRM,并将SLDRM与SWLDRM进行比较仿真实验,仿真实验结果表明SLDRM具有更好的搜索性能。Peer-to-peer is a distributed control network technology, how to enhance file query efficient is where the shoe pinches in Peer to Peer development, sustaining semantic query is one of ways.SWLDRM is a improved modle based on Chord, it distributes files on nodes with DHT arithmetic, and adapts to query accurately, but doesn＇t sustain semantic query. This article uses semantic space form nodes clustering according to stored data interests, and designs Semantic Layer Distributed Route Model. By simulating and analyzing SWLDRM and SLDRM, the experiment results show that the latter has better performance.
