| 摘 要： | 提出了一种基于放大转发的机会协同自动重传请求协议,在提供可靠传输的同时获得了高能效。给出了一种基于马尔科夫链的吞吐量模型和一种能量效率分析模型,分别分析了所提协议的吞吐量和能效性能。Monte Carlo仿真表明理论分析与实际仿真所得到的系统吞吐量性能基本一致,且仿真结果还表明该协议相比传统ARQ协议具有更高的吞吐量和能效性能。

| Abstract: | An opportunistic cooperative ARQ protocol with amplify and forward(AF) relaying is proposed,which obtains high system energy efficiency with reliable transmissions.The system throughput of the proposed protocol is discussed based on a Markov model,and another model for analyzing system energy efficiency is also proposed.Monte Carlo simulations demonstrate that the results derived from theoretical analyses are consistent with that of practical scenario simulations;the results also show that the proposed protocol performs better than the traditional ARQ protocol in terms of system throughput and energy efficiency. |
