QoS-aware service composition in multi-network environment based on genetic algorithm

QoS-aware service composition is one of the most important technologies in SOA. The aim is to compose a new service with the best QoS under the user constraints by a set of atomic services. There are a lot of researches on this topic in recent years. But most of them did not take the effect of the multi-network environment into account and the algorithms took much time when the number of the service candidates was large. In this paper, we present a service composition model in multi-network environment and solve the problem by employing genetic algorithm (GA) within acceptable time. Our approach provides a fast way to find the best solution for QoS-aware service composition in multi-network environment. The experimental results show that our method achieves better performance than other approaches.
