The optional routing optimization strategy of Distributed Mobility Management

This paper presents a review for Distributed Mobility Management (DMM). Mobility Management is one of the key technologies in Mobile Network. DMM can solve the problems of traditional Centralized Mobility Management (CMM) such as non-optimal route and single point of failure and attack. There are several DMM approaches in recent researches. Some are based on MIP and some on PMIP. We summarize and present an optional optimization (O2) strategy in this paper.
