Design and Implementation of Mobile IPv6 Data Communication in Dual Networks

Dual Stack Mobile IPv6 is an extension of Mobile IPv6 to support mobility of devices irrespective of IPv4 and IPv6 Networks. This is implemented by combining different modules. IPv4 private networks are behind Network Address Translation (NAT) devices. So, to bypass the Binding Update and Binding Acknowledgment by NAT, we need to encapsulate it in User Datagram Protocol (UDP) Packets. So, the Dual Stack Mobile IPv6 should support NAT Traversal and Detection. With the support of NAT Detection and Traversal Module in Dual Stack Mobile IPv6, the mobile node is able to move freely from IPv6 Network to IPv4 Network or vice-versa. The main objective of not breaking the connectivity at the time of switching from one network to other is accomplished by NAT Module in Dual Stack Mobile IPv6.
