【摘要】 对G/G/∞排队模型的队列服务时间进行修正,推导出正确的发送概率。利用修正模型分析非理想信道下的IEEE 802.11分布式协调功能无线局域网基本访问机制和RTS/CTS访问机制的饱和吞吐量,并计算出非理想信道下的平均分组时延。通过NS仿真验证该方法的正确性。更多还原

【Abstract】 This paper corrects the service time of G/G/∞ queuing model and gets the accurate result of the transmission probability.Based on the corrected model,the saturation throughput of IEEE 802.11 Distributed Coordinated Function(DCF) WLAN basic access mechanism and RTS/CTS access mechanism is analyzed,and the average packet delay for a lossy channel is derived.The correctness of this method is verified by simulation with NS.更多还原
