This paper describes a new MAC protocol for integrated inter-vehicle and road to vehicle communications called VRCP (Vehicle and Road-side Collaborative MAC Protocol) that achieve high performance in communications. The VRCP uses two channels. In the VRCP, RVC is used for both the access control of IVC and data communications. For the performance evaluations, the autonomous cruising traffic simulator considering the shadowing effect is employed to investigate in realistic traffic conditions. Simulation results show that the performances of the VRCP in the case of using RVC for access control of IVC and another case of using RVC for both the access control of IVC and data communication. In particular, the VRCP can achieve high performance by using RVC for compensate the data of IVC even in the shadowing conditions, compared to the conventional IVC by contention access scheme.
