Mobile Data Offloading: A Host-based Distributed Mobility Management Approach

International audienceWith increasing usage of mobile devices, we are 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 need to be adopted in the evolution of mobile network architectures. Existing IP mobility support protocols rely on centralized mobility anchors that suffer from inefficient routing and scalability issues due to rapidly increasing traffic volumes. In that vein, this article introduces a new IP mobility support protocol that does not rely on a single-handed mobility anchor, but utilizes distributed mobility anchors to overcome the limitations of the existing protocols while providing selective data offloading. We highlight the main features and strengths of the new protocol through qualitative comparisons and simulations
