Theoretical analysis of the modified binary countdown scheme

To design and evaluate the media access control scheme is important for the vehicular ad-hoc network (VANET) systems. As MAC scheme, the modified binary countdown scheme is considered. However, this scheme is not analyzed in theory. In this paper, the average packet acquisition time of the basic modified binary countdown scheme is evaluated by the theoretical analysis. Compared with the results of the computer simulation, the little difference is occurred between the theoretical value and the simulation value occur by the user´s allocation.
