在本文中，我们使用离散马尔可夫链模型来分析无线局域网中CSMA/CA协议的吞吐量，考虑捕获现象，这意味着即使存在其他重叠数据包，具有最强功率的数据包也可以捕获接收器。建立了在存在路径损耗、阴影和瑞利衰落的情况下CSMA/CA协议理论吞吐量的捕获效应模型，并与没有捕获效应的模型进行了比较。
In this paper, we use a discrete Markov chain model to analyze the throughput of CSMA/CA protocol in a wireless local area network considering the capture phenomenon, which means the packet with the strongest power may capture the receiver even in the presence of other overlapping packets. The model of capture effect over the theoretical throughput of CSMA/CA protocol in the presence of path loss, shadowing, and Rayleigh fading is obtained and compared with the model without the capture effect.
