There are several technologies to connect vehicles to networks and the Internet such as Network Mobility (NEMO) and Mobile Ad-hoc Networks (MANET). We investigate the use of both NEMO and MANET for efficient communication in vehicles. A Mobile Gateway manages both the NEMO connectivity and the MANET connectivity and switches path to a destination according to application and network environment requirements. Our results show that this approach is efficient for vehicle networks. Categories and Subject Descriptors: C.2.2Network Operations:Network management General Terms: MANAGEMENT
