论文摘要
对于车辆网络，安全距离很重要，但是现有的空间模型无法表征此参数，尤其是用于车间间通信。这项工作提出了一个基于校长过程的框架，以评估信号分数（SF）的性能，其中硬核距离用于描绘安全距离。通过考虑半圆形和全向天线，我们得出了通信距离的高精确封闭形式的概率密度函数，以获取SF的互补累积分布函数。从理论上讲，派生的表达式表明，安全距离内的最近车辆遵循均匀的分布，而在发射功率方面，SF的上限是一个上限。
For vehicular networks, safety distances are important, but existing spatial models fail to characterize this parameter, especially for inter-lane communications. This work proposes a Matern hard-core processes based framework to appraise the performance of signal fractions (SF), where the hard-core distance is used to depict safety distances. By considering both semicircle and omnidirectional antennas, we derive high-accurate closed-form probability density functions of communication distances to acquire the complementary cumulative distribution function of SF. The derived expressions theoretically demonstrate that the nearest vehicle within the safety distance follows a uniform distribution and there is an upper limit for SF in terms of the transmit power.
