中文说明：带冲突避免的载波侦听多路访问/（CSMA/CA）是一个用于网络使用802.11标准的载波传输网络竞争协议，CSMA／CA，一个节点接收到一个数据包用于发送的那一刻，它做的第一件事是听一个预先指定的时间框架来确定另一个节点在无线范围的广播频道的广播信道。如果广播信道被检测为“空闲”，然后节点可以开始传输数据包，如果广播频道被检测为“忙”，“节点”保存传输，等待一个随机时间框架，然后再检查一遍，以了解该信道是否是免费的。这段时间被称为退避因子。退避因子计算下来使用退避计数器。&；nbsp；
English Description：
Carrier Sense Multiple Access/with Collision Avoidance (CSMA/CA) is a network contention protocol used for carrier transmission in networks using the 802.11 standard.In CSMA/CA, the moment a node receives a packet intended for sending, the first thing it does is to listen to the broadcast channel for a pre-specified time frame to determine if another node is broadcasting on the channel inside the wireless range. If the broadcast channel is detected as "idle," the node can then start transmitting the data packet. If the broadcast channel is detected as "busy," the node holds the transmission, waits for a random time frame and then checks all over again to find o
