QoS-Aware Service Selection in P2P-Based Business Process Frameworks

With the advances and evolution of semantic Web services, service providers need to be more competitive, efficient, flexible, and integrated in the service network at different scenarios, including static and dynamic deployments and interactions. Recently, OWL-S and QoS-aware services have been distinguished due to their significance and their impact on decentralised network. JXTA and BPEL allow peers to cooperate and automate business processes and reengineer their structure, so as to rationally select and make use of all resource in decentralised environment; in addition, they increase efficiency and reduce costs. We incorporated several typical constraints to testify the possibility of the application of QoS-aware services in a P2P network, and enhanced the performance of the relevant prototype.
