摘　　要：结合One-hop和Chord路由机制,考虑实际网络中节点能力的差异,构造一种双层环路由结构,设计相应的区间查询定位和消息广播算法,提出一种基于本体聚类的双层环P2P网络的Web服务发现方法,实现了服务注册节点分类和查询请求迅速准确的定位。模拟实验结果表明,该方法具有较高搜索效率和较短的响应时间,能够显著地提高查询性能。In order to achieve the classification of web services register nodes and exact location of query request, a double- loop routing structure is constructed, the interval query locating and message broadcasting algorithms are designed, and a web service discovery method based on ontology clustering in double - loop P2P networks is presented by combining the lookup protocols of One - hop with Chord and taking into account the ability differences of nodes in the network systems. The experimental results show that this presented method obtains good efficiency and short response time and improve the search performance.
