BAPAWSC: A new dynamic web service composition algorithm in distributed environments

In order to overcome the shortcoming of performance bottleneck and single point of failure in centralized web service systems, a novel distributed dynamic service composition approach that based on Business Abstract Plan (BAP) has been proposed according to the distributed features of heterogeneous information systems. Using this approach, the BAP repository can be expanded automatically by the results of current composite plans, which can increase the response rate of service requests gradually. Simulation results demonstrate that the proposed approach can reduce the average response time of service queries and improve composition efficiency in distributed environments.
