Dynamic mobile IP anchoring

The increase of mobile traffic and the new role of the users as active elements in the network require a new approach for network architectures to adopt more flatten models. However, current mobile IP approaches were developed assuming static and centralized models: a single entity is responsible for the mobile traffic, the signaling and the context information of a large amount of Mobile Nodes. We propose a new host-based mobility approach denoted as Dynamic Mobile IP Anchoring (DMIPA) that distributes mobility management functionalities among Access Routers (ARs) and MNs, and provides dynamic sessions anchoring. DMIPA is envisioned to support these novel flat network architectures, and it is able to provide global IP mobility to the users, independently of the access network, technology and Internet provider. Through an analytical model, we compare DMIPA against Mobile IPv6, which is the standard host-based mobility model for IPv6 networks. The evaluation shows that DMIPA achieves better results regarding the handover delay and the data delivery cost, while the signaling cost can also be reduced in networks with low loss probability.
