基于HARQ的协作与非协作传输能耗比较分析

摘要

This paper analyzed the average total energy consumption of non-cooperative (single-user link ) and cooperative propagation ( MIMO, MISO, SIMO and SISO) based on different HARQ protocols by building the state transition models. Under the interruption probability constraint and the delay constraint, minimized the average total energy consumption of the five propagation methods by optimizing transmission energy and transmission time of each packet. The minimized average total energy consumption of the five propagation methods were compared with each other. The simulation results demonstrate that the performance of non-cooperative is better than cooperative propagation for any HARQ protocol in short transmission distance,while in long transmission distance,the performance order of the mentioned five propagation methods is MIMO, MISO, SIMO, SISO and non-cooperative.%针对无线通信中不同协作方式的HARQ能量消耗问题,建立了协作和非协作HARQ过程的状态转移模型,分别分析了非协作传输(单用户链路)和协作传输(如MIMO、MISO、SIMO及SISO)方式的平均总能量消耗.通过对传输时延和发送能量的联合优化,达到最小化平均总能量消耗的目的,并比较了协作与非协作五种传榆方式的总能耗(energy consumption).仿真结果表明,短距离传输时,非协作传输比协作传榆更节能;在长距离传输时,五种传输方式的能耗由低到高依次分别是MIMO、MISO、SIMO、SISO和非协作传输方式.
