HIERARCHICAL MOBILE IPV6 (HMIP)

This solution is based on a hierarchical structure of the infrastructure where foreign agents are associated with a foreign agent proxy (mobile anchor point MAP) that manages handoff procedures between foreign agents

flowchart BT
A[(HA)]
B((internet))
C{foreign\n agent\n gateway}
D{foreign\n agent\n gateway}
E[foreign\n agent]
F[foreign\n agent]
G[foreign\n agent]
H[foreign\n agent]
I[foreign\n agent]
J[mobile\n node]
A & C & D --> B
E & F & G --> C
H & I --> D
J --> E

the handoff can be

• local subnet handoff local to a MAP
• MAP domain handoff between to different MAPs

The mobile nodes organizes themselves in MAPS dynamically based on service rate and mobility rate
