Abstract
Methods and apparatus for enabling mobility of a node that does not support Mobile IP include sending a node attachment message from an access point to a Foreign Agent indicating that a node has been detected in a vicinity of the Foreign Agent. The Foreign Agent composes and sends a registration request to a Home Agent on behalf of the node. The Home Agent sends a registration reply to the Foreign Agent. The Foreign Agent then sends an attachment acknowledgment message to the access point indicating whether the node is now capable of receiving packets via the Foreign Agent. While the node is visiting the Foreign Agent, the access point redirects packets sent by the node to the Foreign Agent.
