摘要
研究战术数据链自组织-时分多址(S-TDMA)网络机制,根据站点时隙预约及信道预约成功后的利用规律,建立马尔可夫链模型对S-TDMA网络机制进行刻画,利用该模型可全面分析S-TDMA网络机制的时隙预约失败概率、有效吞吐量及传输时延等指标,还可分析相关参数对上述指标的影响。分析表明,S-TDMA体制对于报文报告率等参数较敏感,而对于时隙预约因子等参数不敏感;分析结果还表明,由于采用"使用前预约"的思想,S-TDMA网络机制的有效吞吐率不高。
The self-organized time-division multiple access（S-TDMA） mechanism is studied.According to the time-slot reservation method and the usage of the channel,a Markov chain model is adopted to analyze this mechanism.With the proposed model,the probability of reservation failure,effective throughput and delay could be comprehensively analyzed.The impact of the related factors on the above-mentioned indexes could also be investigated.Analysis results show that this machanism is sensitive to message report rate while relatively insensitive to slot reservation factor,and due to the idea of ＂reservation before usage＂,could provide a not-so-high effective throughput.
