Mobile sensing technologies can collect multiple types of information that are related to the nearby environment using vehicle onboard sensors. However, mobile sensing technologies require robust networks due to unstable performance on vehicle-to-road (V2R) communication. Furthermore, modern IoT systems must connect via secure communication networks to protect service and data. This paper introduces a new configuration of a private V2R wireless communication architecture with two different role wireless links. In our design, the IEEE 802.11ah link discovers another node before entering the high-speed Wi-Fi link that delivers application data. This design attempts to extend the capacity of data transmission even when the vehicle is on the move. We also use the QUIC protocol to exchange application data, encrypt the payloads, and improve the performance in poor-quality networks. We found that the new proposed system can discover other nodes with 800 m or more coverage over the IEEE 802.11ah wireless link. The application data link delivered payloads in the scenarios on a high packet loss network, and it reduced 14.2 times shorter time completion at the maximum.
