Write and test a program to simulate the flow diagram of CSMA/CA in Figure 12.15.

Figure 12.15 Flow diagram of CSMA/CA Station has a frame to send K = 0 Legend K: Number of attempts T: Backoff time IFS: Interframe Space RTS: Request to send CTS: Clear to send Channel free? [false) [true] Carrier sense Wait IFS Choose a random number R between 0 and 2* - 1 and use the Rth slot Contention window Send RTS Wait Tg seconds (Set a timer CTS received [false) [true] Wait IFS before time-out? Send Transmission the frame Set a timer [true] ACK received before time-out? K < limit ? K = K+1 [false] [false] |Itrue] Abort Success
