WSPDS: Web Services Peer-to-Peer Discovery Service

Abstract-- The Web Services infrastructure is a distributed computing environment for service-sharing. In this environment, resource discovery is required as a primitive functionality for users to be able to locate the services, the shared resources. A discovery service with centralized architecture, such as UDDI, restricts the scalability of this environment as it grows to the scales comparable with the size of the web itself. In addition, current extensively used web service standards (e.g. UDDI, WSDL), do not support discovery at a semantic level. In this paper, we introduce WSPDS (Web Services Peer-to-peer Discovery Service), a fully decentralized and interoperable discovery service with semantic-level matching capability. We believe the peer-topeer architecture of the semantic-enabled WSPDS not only satisfies the design requirements for efficient and accurate discovery in distributed environments, but also is compatible with the nature of the Web Services environment as a self-org...
