想请教这里Linux高手一个问题

stefenlin

我在作DA,目前遇见个对我来说很棘手的问题，我想在Linux的Link Layer 下取得数据包发送成功后的ack. 请问高手，在哪可以获得？Tutor建议我在无线网卡驱动(orinoco)里找，我用了printf想显示结果，结果数据包发送成功，可我啥结果也没获得。
想请问，有谁也在作无线网吗？有没有在link layer下好的求FER的方法(我需要ack就是为了求FER)，谢谢。
如果和谁作的课题差不多，我们也可以一起讨论讨论。

Sorry.    For wireless channel, i don't know much. Is there really a ACK for a Request just like what happens in LAN?


Oh, a whitepaper about TCP ACK in wireless

Performance Improvement of 802.11 Wireless Access Network With TCP ACK Agent and Auto-Zoom Backoff Algorithm

10. Capturing packets on wireless LANs  http://www.wireshark.org/faq.html#q10.1


Another option is,  socket programming with PCAP library packet http://www.tcpdump.org/       They works perfectly in ethernet LAN but it is hard to say, anywhere special and different for WLAN.
