Description

Abstract:

                        In this project, to propose  a proactive framework for dynamic service discovery in which candidate services to replace existing services in a service-based application are identified in parallel to the execution of these applications. The identification of services during the execution of service-based applications & also replace services does not satisfy the certain requirements. The proposed method can execute service discovery queries in pull and push mode. The pull mode of query execution is performed by searching service registries to identify services to be bound to an application. The push mode of query execution is based on subscribed services and queries. In both modes of query execution, the identification of services relies on distance-based matching of structural, behavioral, quality, and contextual characteristics of services and applications. It uses complex queries expressed in an XML-based query language. The language allows the representation of structural, behavioral, quality, and contextual characteristics of services and applications & provide better results.
