In this paper, we propose an adaptive intermobility supports scheme for Network-based Localized Mobility Management (NetLMM). The NetLMM approach uses Proxy Mobile IPv6 (PMIPv6) technique and employs a PMIP client to manage a mobile node (MN) within a local mobility domain (LMD). The distinguishing mark is that an MN does not need to have a mobility stack for mobility supports within the NetLMM approach. However, the NetLMM approach has not provided an inter-mobility, where the MN hands off between the LMDs. Thus, in this paper, we propose the adaptive inter-mobility supports scheme where an MN hands off between the LMDs even though the MN does not have the mobility stack. In the proposed scheme, the old LMA recognizes that the MN has been moved into a specific LMA and then the old LMA forwards the packets destined to the MN to the specific LMA. Thus, the proposed scheme provides a seamless handoff service and inter-mobility supports.
