本文提出了IEEE 802.11p MAC子层增强型分布式信道访问（EDCA）机制的吞吐量分析模型。EDCA的特点，如不同的竞争窗口（CW）和仲裁帧间空间（AIFS）为每个访问类别（AC），以及内部冲突的考虑。分析模型既适用于基本访问，也适用于请求-发送/清除-发送（RTS/CTS）访问模式。通过仿真结果验证了该分析模型的准确性。
This paper proposes an analytical model for the throughput of the Enhanced Distributed Channel Access (EDCA)mechanism in IEEE 802.11p MAC sub-layer. Features in EDCA such as different Contention Windows (CW) and Arbitration Interframe Space (AIFS) for each Access Category (AC), and internal collisions are taken into account. The analytical model is suitable for both basic access and the Request-To-Send/Clear-To-Send (RTS/CTS) access mode. The proposed analytical model is validated against simulation results to demonstrate its accuracy.
