According to the concrete conditions of the collision node, it carries on rational adjustment to the size of contention window.

根据发生冲突节点的具体情况，对竞争窗口大小进行合理的调整。

However, it is observed that the primary deficiency of the current MAC protocol is to use the binary increasing-only mechanism. DCF absorbs the number of collisions as the condition to derive the contention window ( CW).

然而，我们可以看到现行MAC协议的主要缺点是使用二进制增长的机制，DCF以冲突次数作为条件来设计竞争窗口（CW）。

The optimal backoff window size and contention window size are given, and the transmission efficiency is calculated by analyzing the collision probability of contention request.

通过对竞争请求的冲突概率进行分析，推出了回退窗口和竞争窗口的最佳分配尺寸，并计算了不同业务流数量下系统可达到的最大传输效率。

We also propose several schemes that regulate backoff contention window adaptively to achieve more fairness between ACs.

再者，我们提出动态允入控制调整方法，来确保无线网路的公平原则。

Based on these observations, a novel adaptive backoff algorithm is proposed, which dynamically adjusts the initial contention window according to the TCP packet length.

据此，提出了一种根据TCP报文长度动态调节初始回退窗口大小的自适应回退MAC协议改进算法。

When the difference of numbers of the packets in each virtual buffer reached the predefined threshold, MAC enlarges the contention window size of the source node, the number of buffered packets of which is more than the other.

当两个虚拟缓冲内的数据包数量之差达到预设阈值时，MAC扩大数据包较多的缓冲区所属流的源节点的竞争窗口大小。

Then a probability model is used to quantitatively analyze the relation between the TCP unfairness and MAC parameters, which shows that the TCP flow fairness heavily correlates with the TCP packet length, and increasing the initial contention window of the MAC protocol can improve the fairness effectively.

然后，利用概率模型定量分析了TCP不公平性与MAC协议参数之间的关系，发现TCP流的公平性与TCP报文长度直接相关，并且增加MAC协议初始竞争窗口的大小能够有效提高公平性。
