Abstract

An Adaptive-Set-Range Rate (ASRR) algorithm, for adaptive set of the transmission range of BSM and the generation rate of data packet, is proposed in this Paper for reason that the safe application of VANETs requiring a periodic interaction of Basic Safety Message (BSM) by vehicles. Considering the safety of vehicles, the proposed ASRR algorithm is used to optimize the generation rate and transmission range of BSM, so as to maximize the utilization of the control channel. In the proposed ASRR algorithm, the time headway is considered as the performance indicators for safety of running vehicles, for calculating the generation rate of data packet, and the functional relationship between the time headway and the generation rate of data packet is set accordingly. Afterwards, the generation rate of data packet is used to calculate the transmission range, considering the consistency with transmission range of neighbor areas. The results of simulation show that, the proposed ASRR algorithm can significantly promote the packet success rate and the channel busy percentage as compared with FRT (fixed transmission range and generation rate of data packet). Thus, the Vehicular ad hoc network (VANETs) is considered as an important part of next generation of automotive system.
