Using optimal constant contention window to optimize performance of WLAN

Novel algorithm of dynamic contention window adjustment for 802.11 DCF

基于竞争窗口动态调整的802.11DCF改进算法

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。

A Multi-Priority Algorithm with RTS Multi-Reservation and Contention Window Self-Adaptive Adjusting in WLAN

RTS多预约和自适应窗口调整的WLAN多优先级算法

Simulation results show that, combining rate adaptation with contention window control can achieve much better network performances, including throughput and fairness, than only using rate adaptation in IEEE 802.11 multi-rate wireless LANs.

模拟实验表明，在多速率无线局域网中，竞争窗口控制算法的引入，可以在已有的速率调整算法的基础上，使网络性能大大提高，获得更好的吞吐量和公平性。

Configurable random backoff process parameters consist of initial contention window, maximum backoff stage number, etc.

可配置的随机回退机制，即使用随机回退机制中的协议参数来进行优先级区分。

But the more smaller in network load, because of the linear decrease mechanism of MILD, the more slower changes in contention window size will reduce the utilization ratio of the channel, cause the deterioration of delay performance.

而MILD的线性下降策略在网络负载较小时，竞争窗口值变化太慢，降低信道的利用率，造成延迟性能的恶化。

Because the law is essentially a businessman autonomy, must be the highest for the concept of autonomy, but the main different is the free consultation on company law in harmony to achieve the objectives of the most common form.

因为公司法从本质上来说是一部商人自治法，必须要以意思自治为最高理念，而且不同主体的自由协商也是公司法上达至和谐目标的最常见形式。
