The Hierarchical Mobile IPv6 (HMIPv6), which is drawn up by the IETF (Internet Engineering Task Force), utilizes the Mobile Anchor Point (MAP) to reduce the considerable number of binding update (BU) messages among the mobile node (MN), the correspondent node (CN), and the home agent (HA). According to the HMIPv6 mechanism, the MAP of higher layer can efficiently reduce the frequency of performing binding update; the higher loading of service is the bottleneck of the whole network. Because the bandwidth of the MAP which can serve is finite, the whole network will be crashed due to the overloading if the MAP serves as the gateway at the same time. This paper proposes a MAP selection mechanism that takes the mobile node's particular characteristics which include the mobility velocity and quantity of communication services into consideration, the proposal can manage the MAPs efficiently. Besides, we design a MAP load balancing mechanism to avoid the network crash due to the overloaded MAP.
