Unformatted text preview: transmission capacity shares to these stations as follows: Station 1: 10%, Station 2: 10%, Station 3: 20%, Station 4: 30%, Station 5: 30% Question # 3 Consider three stations A, B and C communicating over a slotted-ALOHA network with a total capacity of 1Mbits/s. All of the stations send frames (new frames and retransmitted frames) to the network according to Poisson distribution with the following rates: Station A: 0.7 frames/frame time, Station B: 1.6 frames/frame time, Station C: 1.2 frames/frame time Assume that the average frame length is 1000 bits and the MAC layer header is negligible. (a) What is the probability of collision in this network? (b) Assume that station B wants to send a 10Kbit jpeg picture to station A. What is the time required to complete this transmission?...
