1·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。
2·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。
3·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.
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。
