Data streams in two sides of a two-way road endure severe unfairness problem due to the competition of holding channel resource among neighbor vehicles
which leads to very low network performance.In order to solve this problem
the relationship between the packet size and relative velocity of each ways vehicles
and the effect of packet size on the probability of successfully competing for the wireless channel as well as the throughput of each data stream are analyzed in this paper.Based on the analysis
an adaptive packet-size adjusting scheme is proposed to improve the fairness of vehicle networks.The simulation results show that the fairness of competing for the channel has been improved greatly and the throughput of each stream is kept relatively high by this scheme.Finally
the SRTS/SCTS is defined and the procedure of obtaining the relative velocity is given.
