Hi, I want to make clear that, in RTS/CTS mode, if the data packet (which follows the previous rts cts exchange) is lost, whether the consequent retransmission will use a doubled contention window? thanks!

many opportunities out there i think. like UIUC/DSSI, JHU NLP workshop, etc.
Yes, you are right. RTS/CTS/DATA/ACK is a complete phase for one data frame to be sent and received. When the destinated receiver receives a RTS, it waits only for a short interframe space (SIFS) time to send back CTS, all others (if they wish to send) will wait for at least a DIFS time to start. DIFS is about 2 times longer than SIFS, this guarantees that procedure is not interrupted.
Thank you for this information! I visited the website http://www.clsp.jhu.edu/workshops/ws09/ It looks pretty nice. I am writing an email to ask for more information. But it seems the summer workshop is for some inner circle of researchers and aren't really for freelancers like me. I haven't done any serious work in this field, I'm just interested ... it seems to be such a crash course that whirls through different NLP research areas and I don't have the necessary background knowledge and skills
【在 j****a 的大作中提到】 : i think this JHU/NLP is a very nice one. you could get a lot, more than most : internships, from it

true that it's hard to get in. The point is this is serious work and once you get in, you'll work with many great people in this area. Good luck!
