  1. Multihop Radio Access Network (MRAN) Protocol Philipp Hofmann hofmann@docomolab-euro.com AUTOCONF WG, IETF 65, Dallas, Texas 23 March 2006

  2. Relation to AUTOCONF • Autoconfiguration of mobile nodes (MNs) in MANET connected to fixed network • Application scenario • Multiple gateways (GWs) available • GWs are fixed • GWs advertise different prefixes • MNs change gateway frequently • General functionality • GW discovery/selection • Autoconfiguration of global address • Packet forwarding to/from fixed network draft-hofmann-autoconf-mran-00

  3. Design & Evaluation • Design considerations • Decoupled operation of MRAN and MANET routing • Different GW discovery modes • MNs control GW selection • Connection maintenance during MNs’ movement • Support of MANET merging/partitioning • Performance evaluation in testbed • Performance impact of GW discovery & multihop handovers • P. Hofmann, C. Bettstetter, and C. Prehofer, "Performance Impact of Multihop Handovers in an IP-based Multihop Radio Access Network", accepted for ACM Mobile Computing and Communications Review 2006 draft-hofmann-autoconf-mran-00
