The QoS properties of the provided services based on SOA play a significant role in service composition. However in the domain of multimedia service, making the provision of services QoS-aware is still a challenging work. In this paper we present a generic QoS model of service composition, as well as an algorithm to the QoS-aware service problem. The proposed algorithm is designed and implemented based on the concepts of learning automation. It has been rigorously tested and evaluated through extensive simulations. Our results show that the learning automation based approach is scalable and can effectively achieve service composition for QoS requirement satisfaction.
