摘要:
为提高网络能效,提出了一种基于IEEE 802.11 PCF工作模式的并行门限服务轮询(PGP)接入控制策略,用于光载无线分布式天线系统的媒体接入控制中.首先,通过休眠/唤醒和捎带机制降低接入能耗,通过门限服务方式提高数据传输效率,从而实现接入能效的提升;然后,建立平均周期分析模型,得到接入能效与系统负载、数据到达率等参数之间的定量关系闭式表达式;最后,通过仿真实验对所提出的接入策略进行性能测试.测试结果表明,PGP系统接入能效最高可达到PCF的700%和绿色轮询的350%.
Abstract:
To improve the network energy efficiency, an access control protocol named parallel-gated poll(PGP)based on IEEE 802.11 point coordination function(PCF)is proposed for the media access control(MAC)of radio-over-fiber based distributed antenna systems(RoF-DAS). First, the sleep/awake mechanism and the piggyback mechanism are developed to reduce the energy consumption. The parallel gated service mechanism is used to improve the transmit efficiency, and then the access energy efficiency is increased. Secondly, the average period analysis model is built to obtain the closed form expressions for the quantitative relationship among the energy efficiency, the traffic load and the data arrival rate. Finally,the performance of the proposed protocol is tested by simulation experiments. The experimental results demonstrate that the energy efficiency for network access of PGP is 700% of that of the PCF, and 350% of that of the green poll(GP).
