Resource Allocation for D2D-Enabled Communications in Vehicle Platooning

Blog Article

Recent studies have shown that traffic Ski de fond - Equipement - Bottes - Combi safety and efficiency can be substantially improved by vehicle platooning, in which the platoon’ stability is ensured through the exchange of control information among vehicles.So, it is a key issue to share control information efficiently and timely.Proximity-based device-to-device (D2D) communications with high transmission rate, can provide a promising solution to the above issue.

In this paper, a platoon leader evaluation-based two-stage platoon formation algorithm is proposed to form stable platoons, which can significantly reduce the spectrum resource overhead and improve the safety of vehicle platooning.After that, we propose a predecessor-following communication mode-based on D2D, ensuring high-rate transmission of control information.Moreover, we propose time division-based intra-platoon and minimum rate guaranteed inter-platoon resource allocation mechanisms, which aims at allocating resources for D2D users efficiently within the platoon and optimize cellular users’ rate, #Youth Barrel Saddle respectively.

Numerical results show that the proposed mechanism and algorithm can not only significantly improve spectrum resource utilization, but also guarantee the platoon stability.
