Abstract
Methods and apparatus for enabling mobility of a node that does not support Mobile IP through synchronization of access point information (e.g., subnet mapping tables) among AAPs are disclosed. In accordance with one embodiment, an authoritative access point (AAP) maintains access point information for all functioning access points (APs) and sends updates for all additions or other modifications to the continually changing access point information to other AAPs. This is accomplished by sending a copy of its local subnet mapping table to the other AAPs. The AAPs receiving the subnet mapping table then update their subnet mapping tables corresponding to the received subnet mapping table.
