Inter-vehicle P2P communication experimental on-board terminal

It is expected that vehicles have on-board terminals to communicate with the fixed network and also with surrounding vehicles in the near future. This paper explains our developed inter-vehicle P2P (peer-to-peer) communication experimental on-board terminal, we nicknamed it "V-ant", which has the feature of adopting AODV (ad-hoc on-demand distance vector) protocol, control of AODV packets transmission direction using GPS data, and adaptive media switching between vehicle-to-vehicle ad-hoc communication, communication through access points, and PHS (personal handy-phone system in Japan).
