求翻译：如图fig 3：节点s监听信道，设定s节点在当前时隙监听到信道空闲的事件为A，则可知s节点的一跳节点如r, s'和两跳节点如s''和r' 都没有发送数据。是什么意思？

Figure fig: node s to listen to the channel, set s node in the current time slot listen to the channel idle event as a known hop node of s nodes such as r, s' and two-hop node s'' and r 'did not send data.

As fig 3: The node s listening channel s node, set the current time slot heard channel Idle A for the event, you know that s a jump node node such as R, S', and two jump node such as ' ' S and R' are not sending data.

Like chart fig 3: The node s monitor channel, establishes the s node to monitor the channel idle event in the current time slot is A, as soon as then may know the s node to jump node like r, s'he two jumps node like s '' and r' all has not transmitted the data.

Fig 3: node s listening channels, set the s node in the current time slot supervisor heard idle channel events for a, s a start node of the node such as r, s' and two-hop node such as s'' and r' did not send data.
