摘　　要：针对无线网络中ARQ协议的传输能耗,建立了每比特有效数据的等效能耗数学模型和设定了以链路最低能耗为能量有效性的优化目标。并依据传输能耗的研究结论将数据链路层的子包传输机制与物理层的自适应调制编码技术(AMC)相结合,提出了一种基于能量有效性的吞吐量跨层控制协议。该协议以最大化系统吞吐量为目的,并实现了AMC和子包机制的能量有效性控制。仿真结果显示该协议可以使系统吞吐量的性能达到整体最佳和使数据传输能耗达到能量有效性的目标。In this paper,an equivalent energy consumption model of per data bit is founded and the optimum conditions of the lowest energy consumption is proposed from transmission channel in ARQ protocols for wireless systems.a cross-layer control protocol was proposed from the view of energy efficiency,which efficiently combined the subpacket transmission scheme at data link layer and the adaptive modulation and coding （AMC） at physical layer.The cross-layer design protocol is optimized to maximize the system throughput under the optimum conditions of the lowest energy consumption.Simulation show that this new protocol can maximize the system throughput and optimize the energy consumption of the data transmission.
