Leveraging Collaboration of Peer-to-Peer and Web Services

Collaborative usage of peer-to-peer and Web services has been recently paid a lot of attention. Proposed solutions, however, are mainly focused on enhancing service discovery by replacing centralized service registries with distributed peer-to-peer architectures. In this paper, we present a service environment that leverages collaboration of peer-to-peer and Web services further. Our service environment provides Web services an interface for rich interaction with a structured peer-to-peer network that is based on P2P SIP protocol implementation. In addition to service discovery and publishing, Web Services are also able to exploit communities, context information and content available in the peer-to-peer network. Finally, we evaluate how the rich Web service and peer-to-peer interaction, and especially service publishing affects the nodes´ load in a structured peer-to-peer network.
