A mobile node is an Internet Protocol version 6 (IPv6) node that can change its point of attachment to the Internet without disconnecting existing connections with other nodes. A mobile node has the following capabilities.
• Maintaining binding information to inform its home agent of its current location
• Receiving and sending all the packets using the tunnel connection established between it and its home agent to hide its current location and provide transparent access to its communicating peer nodes
• Performing the return routability procedure to communicate with nodes that support the route optimization function to avoid inefficient tunnel communication
