Abstract: One of the key of mobility is the handover's latency. There are many methods with the cost of modification to mobile IP protocol. The paper discusses the route optimization based on MBG to make the handover's latency shorten, if the network's topology can be known in advanced. At the end of this paper the simulation's result is given.
