A Distributed IP Mobility Approach for 3G SAE

Future generations of mobile operator networks, based on an all-IP-based flat architecture and a multitude of different access technologies, require a proper IP-based mobility management in place. In this paper, a scalable and completely distributed mobility management is presented which is based on a Distributed Hash Table data structure. The Distributed IP Mobility Approach (DIMA) remains completely compatible towards Mobile IP and its variants Hierarchical Mobile IP and Proxy Mobile IP. They examine the average service time per packet and the load caused by lookups in the system, by applying a suitable mobility model and by using a traffic model consisting of a mix of representative traffic classes (HTTP, VoIP, Audio and Video streaming).
