QoS-Based web service composition based on genetic algorithm
Quality of service (QoS) is an important issue in the design and management of web service composition. QoS in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. In recent years, the number of available web services has proliferated, and then offered the same services increasingly. The same web ...
متن کاملSemantic Constraint and QoS-Aware Large-Scale Web Service Composition
Service-oriented architecture facilitates the running time of interactions by using business integration on the networks. Currently, web services are considered as the best option to provide Internet services. Due to an increasing number of Web users and the complexity of users’ queries, simple and atomic services are not able to meet the needs of users; and to provide complex services, it requ...
متن کاملOptimal QoS Aware Multi-Path Web Service Composition Using Heuristics Algorithm And Data Mining
In QoS aware service composition, specifically in multiple execution paths compositions, how can we produce optimal composite services that satisfy QoS requirements supplied by clients? Can we generate a solution that simultaneously optimizes all the execution paths, while meeting global QoS constraints imposed by the clients? This paper proposes an optimization mechanism that optimizes the exe...
متن کاملMulti-Path QoS-Aware Service Composition
The goal of QoS-aware service composition is to generate optimal composite services that satisfy QoS requirements defined by clients. However, when compositions contain multiple execution paths, it is difficult to generate a solution that simultaneously optimizes all the execution paths involved in the composition at the same time, while meets global QoS constraints imposed by clients. Furtherm...
