Abstract: This paper first gives the comparison of several existing adaptive multirate protocols.By comparison，the novel adaptive multirate protocol—AMARF is described in detail.Secondly，this paper has implemented the adaptive multirate protocol ARF and AMARF on commercial wireless network card，by modifying the software driver in linux OS.Finally，in the laboratory environment，this paper makes a practical performance measurement for several adaptive multirate protocols，and the measurement result shows that AMARF protocol outperforms others in different channel environments.
Key words: adaptive multirate, AMARF, wireless network measurement
摘要： 首先比较了现有的几种主要的自适应速率协议的特点，并详细阐述了一种新的自适应多速率协议AMARF的原理。其次，基于linux操作系统，通过修改设备驱动程序，在商业无线网卡上实现了ARF和AMARF两种自适应速率算法。最后，在实验室环境下，对各种速率自适应的算法进行了实际的性能测试，测试结果表明：在不同信道环境下，AMARF协议性能较优。
