QoS technology perception-based dynamic web service selection method

Abstract

The invention relates to a dynamic web service selection method, and belongs to the technical field of network service, in particular to a QoS technology perception-based dynamic web service selection method. In the method, the dynamic web service selection is performed by adopting a paper tape model and a method which combines QoS technology and skyline in a database and using a specific dynamicservice selection algorithm. The method can greatly improve the efficiency of service selection and the completeness of a service selection result, and has a wide application prospect.

Description

A dynamic web service selection method based on QoS technology perception Technical field The invention relates to a dynamic web service selection method, in particular to a dynamic web service selection method based on QoS technology perception, and belongs to the technical field of network services. Background technique With the rise of networked applications and the concept of "software as a service", the main forms, operating methods, production methods and use methods of software systems under the Internet environment are undergoing tremendous changes. Building on-demand loosely coupled distributed application systems through service reuse and dynamic aggregation has become an important trend in future network software development. However, with the explosive growth of the number of services, a large number of services with the same function and different non-functional characteristics are distributed on the network. How to choose a better quality service from a set of se...

However, the existing service selection algorithms often only consider the optimal selection in the static service environment, while ignoring the influence of the dynamic service environment on the selection method.
