Abstract
An IEEE 802.11p protocol-based vehicle-to-roadside and vehicle-to-vehicle communication test method oriented to the Internet of Vehicles. The method includes: driving a host vehicle and a target vehicle at a same speed on a road segment; the host vehicle being located behind the target vehicle; a constant distance is maintained between the host vehicle and the target vehicle; the host vehicle is equipped with a host vehicular communication unit, the target vehicle is equipped with a target vehicular communication unit communicating with the host vehicular communication unit; calculating a throughput and a round trip time RTT from the target vehicular communication unit to the host vehicular communication unit; repeating driving the host vehicle and target vehicle N times, and calculating an average throughput and an average round trip time (RTT) of the N times; and calculating a network performance parameter η according to the average throughput and the RTT.
