Exploring a New Framework to Build Mobile QoS-Aware Applications and Services for Future Internet

Abstract

Mobile users are making more demands of common networks by running applications such as network streaming of audio, video as well as immersive gaming that demand a high Quality of Service. One way to address this problem is by making services mobile, such that the services will move closer to the users as they move around. This ensures that low latencies are maintained between the client and server resulting in a better Quality of Service. At present, new architectures such as the Y-Comm framework, attempt to provide a platform to support intelligent service migration mechanisms. However, what is also needed is to provide QoS mechanisms in order to facilitate efficient service migration. This requires techniques to measure the QoS in terms of bandwidth, latency and burst characteristics at various locations to which the server could be migrated. In addition, the emergence of Software Defined Networking as well as new end to end control mechanisms such as the Network Management Control Protocol and the development of new transport protocols will allow a new framework to support mobile QoS-Aware applications and services that will be a key part of the Future Internet. This paper explores the development of a new applications and services framework for Future Internet that replaces the traditional IP framework. New mechanisms are developed to decide when and where to move services and a video on demand scenario is analysed. An analytical model is investigated to provide results based on bandwidth and latency. The results show that this approach is valid and should lead to better QoS and better Quality of Experience for mobile users.
