| 摘 要： | 机器对机器(M2M,machine to machine)通信有着巨大的市场潜力,无线局域网(WLAN)作为3G网络的主要补充必将承载大量M2M业务。针对具有时延容忍、耐性重试等特点的典型的M2M小数据业务,提出了一种大时间尺度退避的IEEE 802.11 DCF网络分析模型,推导了MAC层服务时间的概率分布;建立IPP/G/1/K离散时间排队系统模型,研究了非饱和负载下M2M业务在WLAN非理想信道中传输的QoS性能。算法仿真结果表明,大时间尺度退避机制有效提高了系统的吞吐量,降低了系统阻塞率。

| Abstract: | Machine to machine(M2M) communications had a huge potential market.Wireless local area network(WLAN) as the main complement for 3G networks would carry a lot of M2M services.Considering the characteristics of typical M2M small data service which was delay tolerant and retry patient,a large time-scale backoff algorithm was proposed in the network model of IEEE 802.11 DCF.MAC layer service time probability distribution was derived,and IPP/G/1/K discrete-time queuing model was established in order to analyze t... |
