Problem 8: You have M stations that are implementing a single-frame reservation scheme to access a shared medium. Assume that all stations use the same frame length and that the effect of the propagation delay is negligible. Answer the following: a) If each station is assigned a minislot in the reservation interval with length X. What is the maximum achievable throughput? b) If on average, there are n stations that are active at a single time, what would be the average throughput? Is it greater than the maximum achievable throughput in a)? Why is that? c) If instead of assigning a minislot for each station, each station uses slotted ALOHA to request a minislot. What is the maximum achievable throughput? Is it greater than the maximum achievable throughput in a)? Why is that? d) What is the average throughput when slotted ALOHA is used to request a minislot? Is it greater than the average throughput in b)? Explain
