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。
(S-TDMA) network mechanism of tactical data link is studied. Based on the utilization rules of station slot reservation and channel reservation success, a Markov chain model is established to describe the S-TDMA network mechanism. By using this model The S-TDMA network mechanism can fully analyze the failure probability of slot reservation, effective throughput and transmission delay and other indicators, but also analyze the impact of relevant parameters on the above indicators. The analysis shows that the S-TDMA system is sensitive to parameter such as message reporting rate and insensitive to parameters such as slot reservation factor. The analysis also shows that the S-TDMA network mechanism The effective throughput rate is not high.
