Research on Service Composition Optimization Method Based on Composite Services QoS

With the development of Cloud Computing, Internet of Things, and the advent of the era of Big Data, the types and scale of services are getting larger and larger, and the problem space of service composition is exploding. In order to measure the composite services quality of different combination schemes, this paper shows the calculation method of composite services QoS (Quality of Service), and improves the Ant Colony Algorithm by introducing Skyline calculation to further improve the efficiency of service composition and respond to user quickly. Finally, it is verified on the real QoS data set, and the feasibility and effectiveness of the method are proved through experiments.
