Abstract: In recent years, with the development of advanced highway-vehicle collaboration technology in China, the safety and reliability of intelligent vehicle fleet is vital to improve the transportation efficiency. Therefore, it is necessary to monitor the status of fleet, infrastructure and its operating environment in real time, and then the inspected information is analysed in the edge and cloud for the risk identification. Finally, the analysed results and control orders are feedbacked to fleet immediately to ensure the safe operation of the fleet. However, due to the high cost of wired monitoring equipment and the difficulty of maintenance, a wireless sensor network based on advanced highway-vehicle cooperative system is proposed in this paper. First, a synergistic model of energy and SIR is established based on the power control and regulation. Second, the reliability of communication between sensor network and fleet is ensured, and the energy consumption of network is reduced accordingly. Furthermore, the consideration of SNR is considered to ensure that the sensor nodes can obtain a larger bandwidth, and guarantee the rapid transmission of information. The experimental results show that the method the reliability of information transmission is improved greatly, and the energy consumption of sensor nodes is reduced to prolongs the lifetime of the network.
