IEEE802.11p protocol based vehicle-to-roadside and vehicle-to-vehicle communication test methods oriented to the internet of vehicles

An IEEE 802.11p protocol-based vehicle-to-vehicle communication test method oriented to the Internet of Vehicles, comprising the following steps:

• step 1:
• randomly selecting two vehicles, wherein one vehicle is a host vehicle, the other vehicle is a target vehicle, the host vehicle and the target vehicle are driven at a same speed per hour on a road segment L, the host vehicle is 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, and the host vehicular communication unit and the target vehicular communication unit are capable of communicating with each other using the vehicular communication units;
• step 2:
• calculating a throughput and a round trip time RTT from the target vehicular communication unit to the host vehicular communication unit;
• step 3:
• driving the host vehicle and the target vehicle on the road segment L for N times, and calculating an average throughput and an average round trip time RTT of the N times;
• and
• step 4:
• calculating a network performance parameter η using an equation (1) according to the average throughput and the average round trip time RTT that are obtained through calculation in the foregoing step:
