Resource Allocation for D2D-Enabled Communications in Vehicle Platooning

Blog Article

Recent studies have shown that traffic 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 telemarkskongen flue 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 iphone 13 atlanta optimize cellular users’ rate, respectively.Numerical results show that the proposed mechanism and algorithm can not only significantly improve spectrum resource utilization, but also guarantee the platoon stability.
