  2. Problem statement • A node may select a different IGW for communication efficiency. →　Configure a new global address using a new prefix. • Aim of GAP: • Suppress change in the global address. • Eliminate route re-construction time.

  3. GAP Mechanism A Tunnel through the Internet（IP-IP Capsulation） α AR → IGW IGW-ADV AR Prefix: α α IGW-ADV MN MN α α α MN Distant Vector/MANET routing protocol may run on ARs and IGW.

  4. Attached MN AR MN IGW IGW A procedure of address configuration in GAP Configure a global address IGW_REG Configure a NANET local address IGW_REG_ACK MN_REG MN_REG_ACK IGW_ADV IGW_ADV AR_REG AR_REG_ACK IGW_ADV Configure a global address
