Abstract
The Web services are distributed across the Internet, but the existing Web service discovery is processed in a centralized approach such as UDDI, which has the limitations of single point failure and performance bottleneck. In this paper we propose a distributed XML repository, based on a Peer-to-Peer infrastructure called pXRepository for Web Service discovery. In pXRepository, the service descriptions are managed in a completely decentralized way. Moreover, since the basic Peer-to-Peer routing algorithm cannot be applied directly in the service discovery process, we extend the basic Peer-to-Peer routing algorithm with XML support, which enables pXRepository to support XPath-based queries. Experimental results show that pXRepository has good robustness and scalability.
