This paper describes a new multi-hop communication using heavy vehicles for hopping, and including of this proposed scheme to VRCP that is a protocol integrating inter-vehicle and road to vehicle communications for vehicle safety with vehicle information sharing (VIS). The proposed scheme realizes VIS in neighbor vehicles with three hops by hopping heavy vehicles. From the results of simulation, it is shown that VRCP including multi hop communication achieves lower communication failure rate than VRCP if the penetration rate in heavy vehicles is more than 40%. Also, it is shown that a multi-hop communication is necessary and indispensable to achieve low communication failure rate, and the required frequency bandwidth achieving 10% of communication failure rate is 114 MHz, and the required frequency bandwidthCH achieving 3% of communication failure rate is 218 MHz in the proposed scheme.
