| 摘 要： | 采用二维马尔可夫链模型,计入了超帧中的标记期和硬预留,对系统中的同一优先级竞争接入站点在差错信道下的饱和吞吐量进行研究。分析表明,信道质量较差时短帧比长帧的系统饱和吞吐量大。理论计算结果与NS2软件仿真结果在误差范围内相一致。差错信道条件下存在最优传输帧长,为优化链路控制,提高系统吞吐量提供了理论依据。

| Abstract: | PCA(prioritized contention access) saturation throughput for error channel while stations had same priority in the superframe of BP(beacon period) and hard DRP(distributed reservation protocol) was researched with two dimension Markovian model.The analysis identifies that short frame has bigger saturation throughput than long frame does while there is worse channel condition.The result from theory computing accords with that from NS2 software simulation in the error range.There is optimal frame length in er... |
