Self-Healing in Dynamic Web Service Composition
Journal Title: International Journal on Computer Science and Engineering - Year 2011, Vol 3, Issue 5
Abstract
Web service composition is defined as an orchestration of multiple web services into a single composite web service. Web service composition is done in three ways such as static web service composition, dynamic web service composition, semi dynamic web service composition. The dynamic web service composition is done on the fly. When the user gives the request the dynamic composer searches for suitable web services and it is composed accordingly. When the services composed dynamically they need to execute in different environment. The dynamic web service composition leads to several faults such as poor response, incorrect order, service incompatibility, unavailability etc. If the failure occurs the cause of the failure has to be detected and healed. The healing should be done automatically. Hence this paper focuses on self-healing mechanism for dynamic web service composition. Self healing is a property of autonomic computing which makes the system to heal itself from the faults. This paper focuses on QoS faults. We proposed a self-healing solution for dynamic web service composition faults. We proposed architecture for self-healing which heals the QoS faults in dynamic web service composition. We have given procedure for our healing mechanism.
