摘要

MAC协议设计是vanet中安全消息广播的重要任务。以往的研究工作已经解决了许多基本问题。它们在高动态和密集的车辆环境中表现不佳。本文提出了一种分槽OFDM联合协议，该协议将IEEE 1609.4标准的控制信道划分为多个子信道，用于网络中所有节点，以避免冲突，提高分组传输率。仿真结果表明，该协议具有较高的分组传输率。

A slotted and OFDM federated protocol for safety message broadcasting in VANETs

MAC protocol design is an important task for safety message broadcasting in VANETs. Previous research works have solved many basic problems. They have a poor performance in the high dynamic and dense vehicle environment. This paper proposes a slotted and OFDM federated protocol in which the control channel of IEEE 1609.4 is divided into many sub-channels for all nodes in the network to avoid conflicts and improve packet delivery ratio. Simulation results show that the proposed protocol has a higher performance of packet delivery ratio.
