论文摘要
众所周知，Internet通信中的帧汇总提高了传输效率。但是，这也导致延迟，即某些实时通信是不合适的，因此在效率和延迟之间取消了权衡。在本文中，我们确定了IEEE 802.11 DCF协议下的框架聚合条件，平均有益。为此，我们首先在随机框架中描述IEEE 802.11中的传输时间，然后计算帧的最佳值，这些框架在汇总时将长期节省传输时间。通过数值实验讨论的我们的发现表明，框架聚集减少了传输充血和传输延迟。
It is well known that frame aggregation in Internet communications improves transmission efficiency. However, it also causes a delay that for some real-time communications is inappropriate, thus creating a trade-off between efficiency and delay. In this paper, we establish the conditions for frame aggregation under the IEEE 802.11 DCF protocol to be beneficial on average delay. To do so, we first describe the transmission time in IEEE 802.11 in a stochastic framework and then we calculate the optimal value of the frames that, when aggregated, saves transmission time in the long term. Our findings, discussed with numerical experimentation, show that frame aggregation reduces transmission congestion and transmission delays.
