Distributed Web Service Mechanism Based on Peer to Peer and Chord Protocol

摘要

Although Web Service already can be implemented by decentralized control, its publication and discovery with Universal Description, Discovery and Integration for Web Service is still based on a centralized structure. In this paper, we propose a new mechanism for decentralized Web Service by employing the efficient dynamics performance of Semantic Web and the efficient online explore capabilities of Peer to Peer networks. We furnish enriched semantic Web annotation with domain ontology, which indexes are contained in a distributed hash table based on classified service for efficient publication and discovery for Web Service. Moreover, we have proposed the decentralized Web Service framework mechanism by using classified ontology to coordinate definite requirement.
