摘　　要：针对非结构化对等网络,设计了一种称为I-Wander的Web服务发现方法.将具有相同功能属性的Web服务聚合成社区.查询包在社区间漫游,把漫游过的社区和节点存储起来,构成认识列表.认识列表被逐跳更新,并在查询包相遇时相互交换.查询包在匹配度最高的社区被大量复制扩散,据非功能属性选出最优服务,用于Web服务组合.实验结果表明,服务聚合和认识列表及其交换机制,节省了查询包的探测时间,提高了Web服务查找的效率.A Web service discovery method（I-Wander） based on unstructured P2P network is proposed. The Web services with same functional properties are clustered into a community. While the query packets wandered among these communities, the current community and node are recorded into a known list. The known list is updated in each hop and exchanged when two packets bumped. A query packet is proliferated through the community which most matches against the query. According to the non-functional properties, the best service is elected out for Web service integration. The results of experiments showed that service clustering and experience exchanging cut down the probing cost and enhanced the efficiency of Web service discovery.
