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
