随着iPad2的发布，留下的竞争窗口也将迅速关闭。
Just like with the iPod and iPhone, the competition is left scrambling to catch up. With the release of the iPad 2 scheduled, the window for competitors to remain relevant is closing quickly.
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。
According to the concrete conditions of the collision node, it carries on rational adjustment to the size of contention window.
利用这一模型，分析了包长、纠错编码方式的选取以及竞争窗口长度等重要参数的选取对系统性能的影响。
Using this model, we analyzed the influence of some important parameters, such as packet size, forward error correction coding scheme and contention window size, to the system performance.
