| 摘 要： | IEEE802．11无线局域网标准已得到了广泛应用，在网络线路竞争时要求捕获具有公平性。将两竞争线路在功率受控下的捕获结果与用现行的各种捕获模型进行了仿真比较，表明延迟、功率等捕获模型均不能准确反映线路竞争捕获的公平性。相对而言，一种新的捕获模型——消息重训(messagere training)模型可精确描述802．11接收器的捕获操作。

| Abstract: | IEEE802.11 WLAN has been applied widely, and capture requires fairness when competition exists in net connections. Through comparison of capturing results of two contending connections under controlled power with simulation results obtained using kinds of existing capture models, this paper shows that delay, power models and so on are unable to accurately describe the fairness of properties of the connections contending capture. Relatively, a new model,message retraining, can describe the capture operation of an 802.11 receiver accurately. |
