A QoS-aware system for mobile cloud computing

With the rapid growth of mobile smart phone users, more and more mobile users are using mobile phones to access Internet services. Meanwhile, cloud computing is changing the landscape of Internet services, so as to affect the mobile services. Cloud computing is regarded as the future of mobile. However, cloud computing still faces a number of challenges, one of which is Quality of Services (QoS), that is, how a service provider can ensure QoS of its cloud services, especially for mobile users. In this paper, we present a QoS framework for mobile cloud computing and an adaptive QoS management process to manage QoS assurance in mobile cloud computing environment. Furthermore, we present a QoS management model based on Fuzzy Cognitive Map (FCM). With an example, we evaluate the proposed system and demonstrate its effectiveness and benefits.
