Mobile IP fast data transfer method using cooperation between mobility agents

In a large-scale, high-speed mobile IP network, data packets may be dropped on a foreign agent, which manages location information of many mobile nodes, due to an increase in the load of the visitor list search process. In this paper, we propose a fast data transfer method in mobile IP networks by saving the load of the search processes on the foreign agent using cooperation between mobility agents. In our experiment, the foreign agent using our method can forward all the received packets when one hundred thousand entries are recorded in the visitor list. The mobile IP forwarding routine using our method can process all the packets at any packet rate and any packet size on a fast ethernet LAN.
