摘要：the mobile data traffic has been extremely expanded for years and will remains the high growth rate in a long term. It is believed that distributed mobility management has been developed to be a new trend of designing mobility management scheme to solve the problem caused by the increasing traffic volume. Based on reviewing the characters of distributed mobility management schemes as a model of “access router distributed but location management centralized”, this paper introduces a distributed mobility management scheme called D-PMIPv6 and its route optimization mechanism. A performance analysis will be given, and numerical results show that the route optimization mechanism this paper proposed has a less signaling cost compared with route optimization mechanism for PMIPv6, but reduces the packets delivery cost as the same as route optimization mechanism for PMIPv6.
