Question

A pure ALOHA network transmits 200-bit frames on a shared channel of 200 kbps. What is the throughput if the system (all stations together) produces 1000 frames per second?

Answer 1

To elaborate: Frame transmission time
Tfr= 200/200 kbps or 1 ms.
If the system creates 1000 frames per second, or 1 frame per millisecond, then G = 1
S = G × e−2G = 0.135 (13.5 percent)
This means that,
Throughput =1000 × 0.135 = 135 frames.
