Method for packet communication with mobile node

摘要

Even when a node (10) which can be moved among different networks (20, 21) and which sends a packet including a private address as a sender address sends the packet in either of the networks (20, 21), the sender address of the packet sent by the node (10) is changed to a same global address. The method can prevent that a correspondent node (11) determines a packet from a same node as a packet from a different node due to a difference in their sender addresses, which hardly interrupts communication.
