Abstract:
1. A method for supporting mobility of a Mobile Node (MN) in a multi-hop Internet Protocol (IP) network, comprising: determining, by the MN, that the MN has moved from a source Personal Area Network (PAN) to a target PAN, if a PAN identifier (ID) included in a received beacon signal is different from a previously known PAN ID; sending, by an MN that has moved from the source PAN to the target PAN, a Router Solicitation (RS) message with an option for requesting its profile to a gateway of the target PAN; and receiving, by the MN, a Router Advertisement (RA) message from the gateway in response to the RS message; wherein the RA message includes a home prefix of the MN as the requested profile and an address option that the gateway uniquely assigns to the MN.
