With 802.11a/n
timings and the most reliable ACK coding rate,
On a 20 MHz channel with the standard guard interval,802.11 sends
12 million symbols per second.Thus,if the sender and receiver
have only one coded transmission in play at a time,the cost of a
single bit of feedback could equal the cost of 816 symbols.This
number can be reduced by aggregating many packets to divide the
large constant cost of feedback across more useful bits.We explore
the details of such aggregation in §5.Even for Strider,the code with
the largest packet size of those we considered,transmitted frames
are only on the order of 3750 symbols each,so that a pause for
feedback after each frame would occupy 18% of the total time spent
on transmission plus feedback.
Let
802.11 a / n
计时和最可靠的ACK的编码速率,
与标准20 MHz通道保护间隔,802.11发送
每秒1200万符号.因此,如果发送方和接收方
只有一个编码传输在一次玩,的成本吗
单的反馈可以平等的成本816符号.这
可以减少聚合许多数据包数量来划分
大型固定成本的反馈更有用的部分.我们探索
这种聚合§5的细节.即使对于黾,代码
我们考虑的最大数据包大小,传输帧
只有3750个符号的顺序,这样一个暂停
反馈后每一帧将占总时间的18%
在传输和反馈.
