In recent years, mobile devices have evolved to support an amalgam of multimedia applications and content often delivered by Cloud services. In order for mobile devices to access Cloud resources, a solution for constant and reliable connectivity is required. This issue is being tackled in 5th Generation Networks by the introductions of mechanisms to support seamless handovers between networks thus providing a tighter coupling between Cloud resources and mobiles. This convergence of technologies creates new challenges in the areas of traffic management and QoS provisioning. This presentation explores a novel service delivery framework, centred on the convergence of Mobile Cloud Computing and 5G networks for the purpose of optimising service delivery in a mobile environment. The framework serves as a guideline for identifying different aspects of service provision in a mobile environment. Service delivery mechanisms that are responsible for optimising the Quality-of-Service and managing network traffic are then examined in detail and a solution for managing traffic through dynamic service localisation based on user mobility and device connectivity is presented. A prototype implementation in a virtualised environment as a proof of concept is also discussed. Finally, an analytical model is used to evaluate the modelling of network Quality-of-Service whilst taking into account user mobility.
