In IEEE 802.11p protocol of Vehicular Ad-Hoc network (VANET), the multiple channels are divided into one control channel (CCH) and six service channels (SCHs). CCH is used for broadcasting safety messages related to road conditions, so that CCH access algorithm has great influence on efficiency of VANET. This paper proposes a contention-free bandwidth partition algorithm, which can dynamically partition the CCH interval and bandwidth assigned to on board units (OBUs) located in vehicles according to real-time VANET environments. Meanwhile, a frequency hopping communication scheme based on chaos scrambling is applied to our algorithm to improve the reliability of VANET. The performance of proposed algorithm are verified by theoretical analysis, the results show that it is able to enhance the transmission efficiency of safety packets in CCH with high reliability.
