Question: Three 802.11 stations get frames to transmit at time t=0. The 4th station (AP) has just finished transmitting a long packet at t=0 to Station

Three 802.11 stations get frames to transmit at time t=0. The 4th station (AP) has just finished transmitting a long packet at t=0 to Station 1. The transmission parameters are: Slot time=1, SIFS=1, DIFS=3, CWmin=5, CWmax=7. Assume that the pseudo-random number generated are 1, 3 and 4. The data size for three stations is 4 slots. Draw a transmission diagram. At what time will the three packets get acknowledged assuming RTS/CTS mechanism and no new arrivals?
