分隙ALOHA: 该协议下，用户在产生帧后总是等到下一帧时开始时才发送，所以，对于结构FrameTime_struct，其m_Frame[i]（相对时间）总是为零。发生冲突后同样等待一个随机时间重发。 所以只要满足当前帧时只有一帧发送，就可以发送成功，而不需考虑上一帧时的情况。 -points gap ALOHA : under the agreement, users always have a frame after frame until the next time when this started, so that the structure FrameTime_struct, m_Frame [i] (relative to time) always zero. After the conflict the same time waiting for a random re-issued. Therefore, as long as the current frame to meet only one this, we can successfully sent, and not considering one at the situation.
