Abstract:
Support for mobility has become a key requirement for computer networks. Users now expect to be connected at any time and from anywhere. At the network level, this will be done using vertical handover techniques across multiple network technologies. However at the service level there is no agreed mechanism by which to support mobile users. Current service delivery techniques that depend on overprovisioning are no longer valid as they are inefficient in terms of network resource management. Furthermore, mobile users now want access to demanding applications such as multimedia services i.e., iPlayer, YouTube and 3D-TV. These services often have constraints in terms of bandwidth and latency that need to be properly supported in the mobile environment. This paper outlines the challenges involved in the design of a service delivery model for mobile nodes with high Quality of Service requirements. The proposed approach uses service migration techniques that take into account user mobility and network conditions so as to ensure efficient use of network resources. In this paper, we introduce the novel concept of user clustering to help us decide when and where services should be migrated. We also show how this idea can be used to support a video streaming service.
