In an infinite-population slotted ALOHA system, the mean number of slots a station waits between a collision and its retransmission is 4. Plot the delay versus throughput curve for this system.
Answer to relevant QuestionsHow long does a station, s, have to wait in the worst case before it can start transmitting its frame over a LAN that uses (a) The basic bit-map protocol? (b) Mok and Ward's protocol with permuting virtual station numbers?What properties do the WDMA and GSM channel access protocols have in common? See Chap. 2 for GSM.Two CSMA/CD stations are each trying to transmit long (multi frame) files. After each frame is sent, they contend for the channel, using the binary exponential back off algorithm. What is the probability that the contention ...In Fig. 4-27, four stations, A, B, C, and D, are shown. Which of the last two stations do you think is closest to A and why?Consider the interconnected LANs shown in Fig. 4-44. Assume that hosts a and b are on LAN 1, c is on LAN 2, and d is on LAN 8. Initially, hash tables in all bridges are empty and the spanning tree shown in Fig 4-44(b) is ...
