A Framework to Improve Adaptability in Web Service Composition

摘要

Web service combination,which integrates independent and modular distributed services,has loosely coupled,location transparent,protocol independent and other characteristics,but it is still lack of autonomic,self-adaptive and self-organized characteristics,and it’s difficult to deal with the complex,dynamic,open and uncertain Internet environment. A framework to improve composition adaptability of web services is proposed in the paper. This framework makes use of agents to supervise and manage service composition implementation. It can deal with various service failures,face different circumstances,and ultimately improve the adaptability of service composition in real-time context-aware style. To evaluate the proposed framework,the prototype implementation and data analysis are given at last.
