| 摘 要： | 通过分析和比较IEEE802.11无线局域网分别采用3种典型MAC机制时的TCP性能,深入研究了MAC机制对无线局域网中TCP性能的影响.仿真结果表明,由MAC机制所决定的信道冲突率、MAC帧丢失率、MAC帧传输时延抖动幅度和频率、网络吞吐量和公平性将直接影响无线局域网中TCP的吞吐量、公平性和稳定性.

| Abstract: | Thoroughly researched the effect of MAC mechanism on performance of TCP in WLAN by analyzing and comparing on the TCP performance under three typical MAC mechanism used by IEEE802.11 WLAN.Simulation results indicate,the channel collision ratio,MAC frame lost ratio,MAC frame transmission delay jitter amplitude and frequency,network throughput and fairness which are determined by the MAC mechanism,will impact directly on the throughput,fairness and stability of TCP in WLAN. |

| Keywords: | Wireless LAN Media access control TCP throughput TCP fairness |
