WebB and C will be utilizing CSMA/CA. If one starts transmitting first, the other will back off. If both do happen to transmit at the same time, there should still be no problem in this case. A cannot see the transmission from C (the signal is so weak as to be background noise), and as such should only see the RTS from B. The same is true for D. WebSee Page 1. Hidden Terminal Problem • A and C can’t see each other, both send to B • RTS/CTS can help – Both A and C would send RTS that B would see first – B only responds with one CTS (say, echoing A’s RTS) – C detects that CTS doesn’t match and won’t send 71CBA.
