Latency is a very important metric to be taken into account in the design of the Connected and Automated Driving (CAD) technology. Today, connected vehicles have a dedicated technology named vehicle-to-everything (V2X). Many current research efforts and standardization activities aim to make the next generation of V2X technology able to offer new usages and services, with the main focus being on supporting road safety applications: hazard, obstacle and collision avoidance, etc. To satisfy the real-time constraints of safety applications, Time Division Multiple Access (TDMA) is a widely-used technique to control and share the channel. TDMA-based Medium Access Control (MAC) protocols have resolved many issues in VANETs and shown good performances in the literature by ensuring a bounded access delay to send an emergency message. However, latency can be further improved by eradicating some imperfections in the functionality of these protocols, such as the access collision problem which can occur when two or more vehicles in the same two-hop neighborhood set try to access the same slot at the same time. That is why we recently proposed an Active Signaling-based TDMA MAC protocol, called AS-DTMAC, which operates above the existing DTMAC protocol. In this paper, we analytically study the performance of AS-DMTAC when we have a homogeneous arrival on each time slot with an error in the signaling process.

延迟是互联和自动驾驶（CAD）技术设计中必须考虑的非常重要的指标。如今，联网汽车拥有一种专用技术，称为“车辆到一切（V2X）”。当前的许多研究工作和标准化活动旨在使下一代V2X技术能够提供新的用途和服务，主要侧重于支持道路安全应用：危险，障碍物和避免碰撞等。为了满足实时性由于安全应用的限制，时分多址（TDMA）是控制和共享信道的一种广泛使用的技术。基于TDMA的媒体访问控制（MAC）协议已解决了VANET中的许多问题，并通过确保发送紧急消息的访问延迟受到限制，从而在文献中显示出良好的性能。然而，通过消除这些协议功能上的一些缺陷，可以进一步改善等待时间，例如，当在同一两跳邻域集中的两个或更多车辆尝试同时访问同一时隙时，可能会发生访问冲突问题。这就是为什么我们最近提出了一种基于活动信令的TDMA MAC协议，称为AS-DTMAC，该协议在现有DTMAC协议之上运行。在本文中，我们分析性地研究在每个时隙上均质到达且信令过程存在错误时的AS-DMTAC性能。这就是为什么我们最近提出了一种基于活动信令的TDMA MAC协议，称为AS-DTMAC，该协议在现有DTMAC协议之上运行。在本文中，我们分析性地研究在每个时隙上均质到达且信令过程存在错误时的AS-DMTAC性能。这就是为什么我们最近提出了一种基于活动信令的TDMA MAC协议，称为AS-DTMAC，该协议在现有DTMAC协议之上运行。在本文中，我们分析性地研究在每个时隙上均质到达且信令过程存在错误时的AS-DMTAC性能。
