滑板车到X的通信：天线放置，人体阴影和信道建模
Scooter-to-X Communications: Antenna Placement, Human Body Shadowing, and Channel Modeling
摘要：
在台湾等国家，踏板车比例很高，与踏板车相关的事故是所有交通事故中最严重的伤亡事故。减少事故数量的一种可行方法是利用踏板车和其他车辆之间的短距离无线通信。这将有助于邻近车辆检测到踏板车，反之亦然，从而降低碰撞的可能性。在本文中，我们进行了广泛的测量，以表征摩托车和其他车辆之间的通信链路。我们的研究结果表明，当视线传播路径被滑板车驾驶员（也可能是乘客）的身体阻挡时，人体的阴影会导致显著的信号衰减，平均范围为9至18 dB，呈现出滑板车特有的具有挑战性的信道特性。此外，我们进行了模拟，这表明，它是必要的，将身体阴影效果，以获得逼真的模拟结果。我们还开发了一个模型，以确定是否人体阴影是有效的，给定的相对位置的发射器和接收器。
英文摘要：
In countries such as Taiwan, with a high percentage of scooters, scooter-related accidents are responsible for most injuries and deaths of all traffic accidents. One viable approach to reduce the number of accidents is to utilize short-range wireless communications between the scooter and other vehicles. This would help neighboring vehicles to detect the scooter and vice-versa, thus reducing the probability of a collision. In this paper, we perform extensive measurements to characterize communication links between a scooter and other vehicles. Our results suggest that, when the line-of-sight propagation path is blocked by the body of the scooter driver (and possibly also a passenger), shadowing of the human body results in significant signal attenuation, ranging from 9 to 18 dB on average, presenting challenging channel characteristics unique to scooters. In addition, we perform simulations, which show that it is imperative to incorporate the body shadowing effect to obtain realistic simulation results. We also develop a model to determine whether human body shadowing is in effect, given the relative positions of the transmitter and the receiver.
