Video is a major challenge for the future mobile
Internet as it is foreseen to account for close to 64% percent of
consumer mobile traffic by 2013. However, the current Internet,
and in particular the mobile Internet, was not designed with video
requirements in mind and, as a consequence, its architecture is
very inefficient when handling this type of traffic. This paper
presents a novel mobility architecture inspired by the Distributed
Mobility Management paradigm, capable of coping with the
future video traffic demands, in a distributed and more scalable
way. In the proposed solution, mobility support services are
spread among several nodes at the edge of the network, thus
realizing a flatter architecture and pushing services closer to the
terminals. Our approach overcomes some of the major limitations
of centralized IP mobility management solutions, by extending
existing standard protocols.
