Vehicle-to-vehicle communication channel measurements on a vertical curve road

Vehicle-to-Vehicle (V2V) communication channel measurements were carried out in different environments such as urban, suburban, rural, highway, tunnel, and overpass. The roads these have generally flat terrain. However, there are horizontal or vertical curve that been little focused the literature. In this study, we performed two V2V on a vertical-curve road rural environment to show how received signal strength changes with distance between transmitter receiver. path loss exponent of log-distance model was calculated by using least-square method. According results, exponents estimated 7.53 7.61 78% 83% fitting performances for measurements. literature, however, propagation obtained up 6.13, especially straight road. Thus, our findings cause 15-20 dB more attenuation than roads. As result, should be investigated included existing wireless simulators better real authors contend study will aid improving modeling communication.
