Q
A slotted ALOHA network transmits 200-bit frames using a shared channel with a 200-kbps bandwidth. Find the throughput if the system (all stations together) produces 500 frames per second.
AA. 92 frames
BB. 368 frames
CC. 276 frames
DD. 151 frames
Correct Answer:
D. D. 151 frames

G=1/2 S = G × e−G = 0.303 (30.3 percent) Throughput is 500 × 0.0303 = 151.
