Distributed Mobility Management for Mobile Data Offloading

Past

Abstract: With increasing usage of mobile devices like tablets and smartphones, we have been witnessing an explosion of mobile Internet traffic. In order to cope with recent traffic growth, current mobile network architectures are being flattened and IP mobility support protocols are thus required to be adopted in the evolution of mobile network architectures. Existing IP mobility support protocols developed by the IETF rely on centralized mobility anchors that suffer from inefficient routing and scalability issues due to rapidly increasing traffic volumes over mobile networks. In that vein, distributed mobility management (DMM) is a new approach attracting attention from telecommunication and Internet communities, as it is more appropriate for the recent explosion of mobile Internet traffic. In this talk, current activities of the IETF standardization and possible two different approaches are presented with comparison results showing features of DMM against the existing mobility support protocols.
