无线网络已经与有线互联网快速集成并且已经被广泛部署。特别地，IEEE 802.11b WLAN是当今最广泛的无线网络。IEEE 802.11b WLAN支持多种传输速率，并且通过自动速率控制算法以自适应方式选择速率。这种自动速率控制算法对IEEE 802.11b无线局域网的整体系统性能有着重要的影响。在本文中，我们研究了无线局域网的性能方面的自动速率控制算法，特别是ARF方案，这是最流行的自动速率控制算法在802.11b的无线局域网产品。实验结果表明，ARF方案在节点位置引起的信号噪声中具有良好的性能。然而，ARF方案严重降低系统性能时，多个节点竞争获得无线信道和数据包丢失，由于信号冲突。
Wireless networks have been rapidly integrated with the wired Internet and have been widely deployed. In particular, IEEE 802.11b WLAN is the most widespread wireless network today. The IEEE 802.11b WLAN supports multiple transmission rates and the rate is chosen in an adaptive manner by an auto rate control algorithm. This auto rate control algorithm deeply affects the total system performance of the IEEE 802.11b WLAN. In this paper, we examine the WLAN performance with regard to the auto rate control algorithm, especially the ARF scheme, which is the most popular auto rate control algorithm in 802.11b based WLAN products. The experimental results indicate that the ARF scheme works well in the face of signal noise due to node location. However, the ARF scheme severely degrades system performance when multiple nodes contend to obtain the wireless channel and the packet is lost due to signal collision.
