摘要: 针对超宽带多跳无线网络,对中继节点参与ARQ机制的可行性进行了研究。在现有研究的基础上结合部分窗口多拒绝ARQ设计出一个能使节点兼顾终端和中继节点ARQ机制的RLC子层协议。接着在对超宽带室内视距((LOS)信道模型理论分析的基础上,针对典型的两跳网络,对比了使用中继ARQ和不使用中继ARQ两种情况下得到的仿真结果,证明了中继ARQ能提高超宽带多跳无线网络的吞吐率和时延性能。

Abstract: This paper did some researches on the ARQ mechanisms which provides the probability of involving the relay nodes into the mechanisms for ultra-wideband multi-hop wireless network,and based on the researches designed a RLC sublayer combining PWMA and Relay ARQ, which can perform as both of the end node and the relay node. Follow this,this paper made a academic analysis of the ultra wideband wireless channel models and simulated the network model under ordinary circumstances and the network model which used ARQ mechanism designed in this paper for representative two-hop wireless network,Compared the simulation results,got the conclusion that using ARQ mechanism designed for ultra-wideband multi-hop network in this paper significantly enhances the throughput and time delay characteristic of the system.
