Time-Dependent Performance Modeling for Platooning Communications at Intersection

With the development of Internet Vehicles, platooning strategy has been widely studied as potential approach to ensure safety autonomous driving. Vehicles in form platoon adopt 802.11p exchange messages through vehicle-to-vehicle (V2V) communications. When multiple platoons arrive at an intersection, leader vehicle each adjusts its movement characteristics that it can cross and thus following vehicles have adjust their accordingly. In this case, time-varying connectivity among leads significant nonstationary performance change communications, which may incur issues. article, we construct time-dependent model evaluate communication intersection based on initial characteristics. We first consider behaviors including turning, accelerating, decelerating, stopping well periodic traffic lights a then establish hearing network reflect vehicles. Afterward, pointwise stationary fluid flow approximation (PSFFA) behavior transmission queue. Then, four access categories (ACs) continuous backoff freezing models describe process 802.11p. Finally, model, packet delay (PTD) delivery ratio (PDR) are derived. The accuracy our proposed is verified by comparing simulation results with analytical results.
