Research and development the methods of quality of service provision in Mobile Cloud systems

摘要

Mobile Cloud Computing (MCC) is an integration of cloud computing in the mobile environment, which is used to improve the overall performance of the mobile devices. The rapid growth of cloud computing and mobile Internet services has triggered the emergence of mobile cloud services. Among many challenges, QoS management is one of the crucial issues for mobile cloud services. Here the survey of the current research related to QoS provision in mobile cloud computing is presented. The provision of QoS in mobile cloud computing is a challenging task. This is because of the dynamic characteristics of mobile networks and limited resources of mobile devices such as bandwidth, delay, packet loss ratio, battery life, storage capacity, computational power, security, etc. Also we present a cloud aware multimedia, which addresses how multimedia services and applications, such as storage and sharing, authoring and mashup, adaptation and delivery, and rendering and retrieval, can optimally utilize cloud-computing resources to achieve better quality of experience (QoE). The traffic of Lviv Polytechnic enterprise network have been analyzed. Simulation model processing of traffic in queues heterogeneity network on the basis of services priorities has been developed.
