Connected car has become one of emerging technology in the automotive industries and vehicular communication studies on the other hand, has become one heavily researched topic in academia which focuses on the performance of various parameters upon vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) communication-based in the IEEE 802.11p vehicular communication studies. In urban environment, obstructions from existence of building, trees, street's layout and other obstruction or objects can strongly influence the receive signal levels at 2.4 GHz frequency band. To ensure reliable and stable communication link for efficient future deployments of cooperative RSUs deployments, will require analyses on the signal strength upon environments that generally characterized by challenging propagation conditions. This article presents the results of experimental field testing of signal characteristics of different types of road topology such as grass, gravel and tar surface on open field environment. The results show that road topology or streets layout have an effect on V2I communication and the attenuation resulted from certain types of road's surface can give significant impact on signal propagation. |
