Abstract
A method of providing mobility support to Internet Protocol version 6 (IPv6) using filtering technology is disclosed. The method comprises the steps of: providing a filter layer below the internet layer and above the network access layer in the TCP/IP stack; and modifying the packets using the filter layer. The step of modifying packets further comprises the steps of detecting the movement of a mobile node, and updating the movement of the mobile node to other nodes. The step of detecting the movement of the mobile node further comprises a step of replacing the prefix in the receiving packets before passing the receiving packets to the non-mobility-capable IPv6 module of the internet layer for hiding the movement of the mobile node; The step of modifying the packets also comprises the steps of adding extension headers to the packets, deleting extension headers from the packets and replacing IP addresses of the packets for the survivability of the ongoing connections.
