Summary: 
In the gauge of IMT-2000, Mobile IP based location management is standardized. The cellular network of IMT-2000 holds many users and covers a large area. In large-scale Mobile IP networks, such as IMT-2000, a foreign agent may manage many mobile nodes by the visitor list and its forwarding performance degrades owing to the list search overload. In this paper, we propose a fast data transfer method in Mobile IP networks by reducing the load of the search processes on the foreign agent using cooperation between mobility agents. In our experiments, we measured the packet forwarding performance and the packet forwarding process time. The results indicate the possibility of the performance degradation owing to the part of the registered mobile nodes in the visitor list. We verify that the foreign agent using our method can forward all the received packets on Fast Ethernet LAN when one million entries are recorded in the visitor list.
