英文摘要	Rate adaptation mechanism can significantly impact the performance of wireless networks. Most existing rate adaptation mechanisms change bitrates based on wireless link quality to achieve higher throughput. Frame delivery ratio(FDR) is a widely-used link quality metric. However, FDR can be affected by different reasons such as channel fading, packet collisions, etc. So when FDR falls, rate adaptation mechanisms should not always reduce the transmission bitrate. We present the concept of inherent FDR(iFDR) to reflect the inherent link quality which is not affected by packet collisions. And based on this new metric, we present a new rate adaptation mechanism which can achieve over 40% improvement compared to traditional ones. ? 2013 IEEE.; EI; 0
