For p-persistent CSMA, consider the following situation. A station is ready to transmit and is listening to the current transmission. No other station is ready to transmit, and there will be no other transmission for an indefinite period. If the time unit used in the protocol is T, show that the average number of iterations of step 1 of the protocol is 1>p and that therefore the expected time that the station will have to wait after the current transmission is T a 1

P - 1b. Hint: Use the equality a



i=1 iXi-1 =
