A Measurement Based Shadow Fading Model for Vehicle-to-Vehicle Network Simulations

Figure 4

a, b, and c represent highway data, and d, e, and f represent urban data. In (a) and (d) inset plots show channel gain for the overall measurement data as a function of direct distance between TX and RX. The slopes are provided up to the distance where no sample is below the noise. Large plot is the histogram of channel gains taken from log spaced distance bin,  m in (a) and  m in (d), marked by vertical lines in the inset plot. The LOS and OLOS data is treated together in these figure; (b) and (e) show histogram of the same channel gains shown in (a) and (d), when separated as LOS and NLOS, pdf fitting the Gaussian distribution; (c) and (f) show CDF fitting the log-normal distribution with % confidence interval.
