A IEEE 802.11 Problem Consider the DCF MAC in IEEE 802.11 using CSMA/CA with RTS/CTS. It is known that RTS length = 20 bytes CTS length = 14 bytes ACK length = 14 bytes SIFS Time = 16s DIFS Time = 34s (1)Sketch a time diagram to show the process of a normal data transmission between a sender and a receiver. Please show the appropriate inter-frame spacing (i.e., DIFS and SIFS). Assume the medium is idle every time when the sender senses the channel. (2)Suppose a station has 1,000 bytes of data to transmit in a data frame. Each data frame has a 30-byte header and a 4-byte trailer. Assume that the medium is idle and all other stations do not have data to transmit at this moment. The transmission rate is 10Mbps.
