A QoS-Aware Decentralized Service Composition Method in Mobile Networks

Nianhua Yang, Qi Li
2017 International Journal of u- and e- Service, Science and Technology  
The service composition scheme for a task is generated dynamically according to the environment of mobile networks in real-time.  ...  In mobile networks, service composition usually depends on a predefined composition model or a centralized communication node.  ...  The QoS of a service may be changed under different execution load. This paper proposes a personalized QoS aware dynamic service composition method in a mobile network.  ...
