Focus on inter-domain handover optimization Problem Statement: Inter-domain handover optimization cannot be solved solely by existing mobility management protocols Requires SA between mobility agents across domains Different domains may use different M-M protocols (e.g., CMIP??PMIP handover optimization) MPA’s ability to work across multiple-domains can enhance performance of inter-domain handover MPA as a helper for existing M-M protocols for inter-domain handover More focus on pre-authorization and proactive handover tunneling part of MPA for inter-domain handover optimization Pre-authentication signaling is being discussed in IETF / IEEE Possible Research topics: Co-existence with FMIPv6, PMIP and 802.21 for inter-domain handover optimization |
