Mobile Adhoc Network (MANET) routing protocol and NEMO basic support protocol are considered key technologies for vehicle networks. Cooperation between MANET and NEMO (MANEMO) brings several benefits especially for route optimization and multihoming. We setup a real-field testbed on the ANEMONE testbed. In our system, a mobile router has 3 egress interfaces, which is 3G and Wifi to connect the Internet, and other Wifi to connect to Optimized link State Routeing (OLSR) network. All of these interfaces are utilized simultaneously for Inter-vehicle communication. The experimentation results show that MANEMO allows to improve the overall network performance in term of bandwidth and delay.
