摘要/Abstract

摘要： 提出一种通过最优化网络的目标误包率来降低丢包率的方法. 物理层采用自适应调制编码方式，数据链
路层采用有限长数据缓冲区，并改变了原有网络中固定的目标误包率值. 在不同的网络参数，如网络的信噪比、功
率、带宽、包到达率等条件下，考察网络的丢包率随目标误包率的变化，总结其变化规律，并根据黄金分割法寻找
最佳的目标误包率，使得丢包率达到最小，即网络吞吐量达到最大.

关键词: 自适应调制, 跨层设计, 黄金分割法, 有限长缓冲区

Abstract: A cross-layer design is developed to reduce the packet loss rate through optimization of the network target PER. Adaptive modulation and coding (AMC) is applied on the physical layer, and a limited data buffer applied on the data link layer to change the fixed target PER of the original network. The network packet
loss rate is studied with the changing target PER beyond different network parameters including the network signal-to-noise ratio, power, bandwidth, and packet arriving rate. The changing rule is then derived. The golden selection method is chosen in search of the optimal target PER to minimize the package loss rate, or equivalently, namely maximize the network throughput.

Key words: adaptive modulation and coding (AMC), cross-layer design, golden selection method, finite buffer
