I-Wander: A Web Service Discovery Method for Unstructured P2P Network

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.
