Question: Let's say that an access point (X in this case) and two wireless nodes make up a wireless network (denoted as A and B respectively).

Let's say that an access point (X in this case) and two wireless nodes make up a wireless network (denoted as A and B respectively). Suppose that wireless nodes A and B are unable to hear X, but they can hear X. (i.e. X can hear A and B). Suppose

-A packet is being sent by X to another node at time 0s, and it is finished at time 100s.

-A packet at A becomes available for transmission at time 20s. A needs 150 s to send this packet.

-A packet at B becomes available for transmission at time 60s, and B requires 100s to send its packet.

-Backoff timers should be set to 40s and 60s, respectively, for A and B.

1) Draw the topology outlined above, taking into account the coverage of wireless nodes X, A, and B.

2) Examine the transmission scenario mentioned above and describe the transmission process. Indicate which node begins to sense and transmit at what time and for how long in your description. Start your description in the network at time zero. Consider a network that only employs CSMA/CA and not the RTS/CTS protocol.
