Consider the topology shown in Figure 3. Transmitters A, B and C are communicating with receivers D, E, and F respectively. Dotted circles indicate the range of communication for each transmitter.

Consider the topology shown in Figure 3. Transmitters A, B and C are communicating with receivers D, E, and F respectively. Dotted circles indicate the range of communication for each transmitter. Specifically, transmitters A and C can sense B, but they cannot sense each other. However, B can sense both A and C. Assume that all transmitters are running basid MACA (with RTS, CTS and Binary exponential backoff protocol for channel contention. (a) Comment on the fairness of the three flows. Do you think the middle flow (B E) gets a fair share (1/3 of the channel time)? Explain why or why not. Assume all flows are fully backlogged (they have packets to be sent constantly) (b) IfB does not get a fair share, suggest two possible methods to improve the fairness If B does get a fair share, please ignore this question. > Figure 3 Consider the topology shown in Figure 3.
