The mobility of service providers brings new features into the research of dynamic network based service composition. From an optimistic perspective, the mobility of services could benefit the optimization of service composition, if properly handled. Therefore, the impacts of node mobility on the dynamic network based service composition are investigated. Then, a movement-assisted optimization method, namely MASCO, is proposed to improve the performance of the composited services by minimizing the length of data stream and the hop-counts of the service routes in the underlying networks. The correctness and efficiency of the proposed method are then verified through theoretical analysis and computer simulations.
