Research on service organization based on decorator pattern

Abstract

With the development of web service applications, how to improve the efficiency of service discovery is an important research work in service computing era. Based on the service clusters which are formed through service clustering, this paper uses the Decorator Pattern ideology to organize the service clusters according to the collaborative relationships between them. The tree structure is used to express the organized service clusters with certain correlations, and it helps to realize service discovery efficiently. It also discusses how to add new services to the service cluster organization dynamically. The experiment results show the method can enhance the efficiency of services (atomic and composite services) discovery.
