Internet WiFi WiFi Cellular Cellular Car-D ������������������������������������������������������� MR MR NEMO: Connect IVN to the Internet •Connected via cellular phone using NEMO •Can communicate with Car-C as a short cut path NEMO: Connect IVN to the Internet (L3 MANET) AP WiFi WiFi Cellular Cellular WiFi WiFi Cellular Cellular WiFi WiFi Cellular Cellular Car-C Car-A Car-B MR MR MR MR MR MR •Connected via cellular phone using NEMO •Connected via WiFi (direct) using NEMO •Connected via WiFi (L2 MANET) using NEMO •Can communicate with Car-D as a short cut path (L3 MANET) Proposition: A vehicle uses any communication media seamlessly. Solution: iCAR introduces NEMO to connect IVN to the Internet. • Movement: CoA, which vehicle want to use, is changed. • When a vehicle moves, it report it to its HA. • Packet will be delivered via a HA. CN AP Internet WiFi Cellular AP MR HA WiFi Cellular MR MR CN assume that the vehicle is always located behind of HA. 2004/09/22 11

Internet WiFi WiFi Cellular Cellular Car-D ������������������������������������������������������� MR MR L2.5 MANET: Infrastructureless communication •Connected via cellular phone using NEMO •Can communicate with Car-C as a short cut path L2.5 MANET: Infrastructureless communication (L3 MANET) AP WiFi WiFi Cellular Cellular WiFi WiFi Cellular Cellular WiFi WiFi Cellular Cellular Car-C Car-A Car-B MR MR MR MR MR MR •Connected via cellular phone using NEMO •Connected via WiFi (direct) using NEMO •Connected via WiFi (L2 MANET) using NEMO •Can communicate with Car-D as a short cut path (L3 MANET) Proposition: Vehicles prefer to connect via a wideband media. Solution: iCAR introduces L2.5 MANET to expand BB media coverage . • Global MANET segment is constructed with AP as a center. • Local MANET segment is constructed with a vehicle as a center. • Local MANET segment is twice bigger than Global MANET segment to follow general IPv6 manner. • Reactive MANET algorithm can be applied to L2.5 MANET. • MANET segment acts as “segment”.

Solution: iCAR introduces L3 MANET to establish a shortcut routing path . • By default, a vehicle supports NEMO. • When two vehicles know routes which can reach each other, it can be “shortcut” paths. • Any dynamic routing protocol can be use to make shortcuts. But MANET protocols work well than others due to dynamicity. • Proactive MANET algorithm can be applied. • Bidirectional path is necessary. • MANET have to have hop limitation. In addition, route information must not redistribute. Internet CN AP AP WiFi Cellular Shortcut WiFi Cellular MR WiFi Cellular MR WiFi Cellular MR MR WiFi Cellular MR 2004/09/22 13
