Mobile IP using private IP address through stateful network address translation

Mobile networking is becoming popular. The increase in mobile communication makes the lacking problem in number of addresses for IPv4 more serious. To solve this problem, this paper proposes an approach to fulfill a mobile JP protocol by using a stateful NAT (Network address Translation) technology. This approach is able to communicate through information sharing by the NAT address mapping between HA and FA. Therefore, the preferred protocol is not requiring an additional procedure between HA and FA for processing, which relate the mobiIity and it´s showing a normal procedure of the mobile IP. This paper presents a detailed design of the statful NAT approach.
