Abstract

Decentralized Environmental Notification Message (DENM) retransmission schemes have been suggested to increase the Packet Delivery Ratio (PDR) for DENMs, they compromise communication performance due to resource collisions with Cooperative Awareness Messages (CAM) in mixed-traffic environments. To address this issue, this letter proposes the Adaptive DENM Retransmission (ADR) scheme, which adaptively adjusts DENM retransmission resources based on the Channel Busy Ratio (CBR) estimated by the transmitting user equipment. Simulation results show that the ADR scheme improves PDR for both CAMs and DENMs, with greater improvements in congested wireless channels.
提高混合V2X业务可靠性的自适应DENM重传
分散式环境通知消息(DENM)重传方案被建议用于提高DENM的分组交付率(PDR),但在混合流量环境中,由于资源冲突和协同感知消息(CAM)影响了通信性能。为了解决这一问题,本文提出了自适应DENM重传(ADR)方案,该方案根据发送用户设备估计的信道忙比(CBR)自适应调整DENM重传资源。仿真结果表明,ADR方案提高了CAMs和denm的PDR性能,在拥塞无线信道中有较大的改善。

期刊介绍: The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
