    摘要:

    数据传输可靠性已成为车联网研究的热点问题,本文首先给出了车辆之间数据传输可靠性的评价方法,并结合小波变换和群蚊子算法对数据评估模型进行求解,同时通过引入分类机制和决策权来引导搜索方向,以此加快算法收敛速度。最后利用仿真实验平台深入研究了影响该算法的关键因素,并讨论了数据包大小、车辆间距、发送功率和车辆速度与数据成功发送率之间的关系。与其他算法比较,该算法显示出较好适应性。

    Abstract:

    The reliability of data transmission has become a hot issue of car networking. The reliability method of data transmission between cars is proposed in this paper, and it is solved with wavelet transform and multi-mosquito algorithm. At the same time, the search direction is introduced by the allocation mechanism and decision-making power to guide, which is in order to accelerate the convergence speed of this algorithm. Finally, the simulation experiments are conducted to study the key influence factors, and the relationships between packet size, vehicle spacing, transmit power, vehicle speed and data success rate. Compared to other algorithm, the result shows that this algorithm has better adaptability.
